This patch converts rfc4106-gcm-aesni to the new AEAD interface.
The low-level interface remains as is for now because we can't
touch it until cryptd itself is upgraded.
In the conversion I've also removed the duplicate copy of the
context in the top-level algorithm. Now all processing is carried
out in the low-level __driver-gcm-aes-aesni algorithm.

We observe a "Zero PT_NOTE entries found" warning when vmcore_init()
is running on the dump-capture kernel. Actually the PT_NOTE segments
is not empty, but the entries generated by crash_save_cpu() are not
flushed to the memory before we reset these cores. So we should flush
the l1 cache as what we do in cpu hotplug. With this change, we can
also kill the mpc85xx_smp_flush_dcache_kexec() since that becomes
unnecessary.
Please note: this only fix the issue on e500 core, we still need to
implement the function to flush the l2 cache for the e500mc core.
Fortunately we already had proposing patch for this support [1].
Hope we can fix this issue for e500mc after that merged.

This patch implements PAGE_EXEC capability on the 8xx.
All pages PP exec bits are set to 000, which means Execute for
Supervisor and no Execute for User.
Then we use the APG to say whether accesses are according to Page
rules, "all Supervisor" rules (Exec for all) and
"all User" rules (Exec for noone)
Therefore, we define 4 APG groups. msb is _PAGE_EXEC,
lsb is _PAGE_USER. MI_AP is initialised as follows:
GP0 (00) => Not User, no exec => 11 (all accesses performed as user)
GP1 (01) => User but no exec => 11 (all accesses performed as user)
GP2 (10) => Not User, exec => 01 (rights according to page definition)
GP3 (11) => User, exec => 00 (all accesses performed as supervisor)

Use of APG for handling PAGE_USER.
All pages PP exec bits are set to either 000 or 011, which means
respectively RW for Supervisor and no access for User, or RO for
Supervisor and no access for user.
Then we use the APG to say whether accesses are according to
Page rules or "all Supervisor" rules (Access to all)
Therefore, we define 2 APG groups corresponding to _PAGE_USER.
Mx_AP are initialised as follows:
GP0 => No user => 01 (all accesses performed according
to page definition)
GP1 => User => 00 (all accesses performed as supervisor
according to page definition)
This removes the special 8xx handling in pte_update()

By default, TASK_SIZE is set to 0x80000000 for PPC_8xx, which is most
likely sufficient for most cases. However, kernel configuration allows
to set TASK_SIZE to another value, so the 8xx shall handle it.
This patch also takes into account the case of PAGE_OFFSET lower than
0x80000000, allthought most of the time it is equal to 0xC0000000

CR only needs to be preserved when checking if we are handling a kernel address.
So we can preserve CR in a register:
- In ITLBMiss, check is done only when CONFIG_MODULES is defined. Otherwise we
don't need to do anything at all with CR.
- We use r10, then we reload SRR0/MD_EPN into r10 when CR is restored

The Odroid XU3 Lite is almost the same as XU3, except:
1. Lower CPU frequencies (1.8 GHz for A15 and 1.3 GHz for A7, instead of
2.0 GHz and 1.4 GHz).
2. No DisplayPort.
3. No TI INA231 energy measurement sensors.
This patch moves common nodes (which is almost everything) to a common
DTSI file and adds a new XU3 Lite DTS.
Currently in comparison to XU3, only the INA231 sensors are disabled to
remove the warning:

PWM output wasn't working because it wasn't hooked up to its pincontrol.
This patch:
- hooks up PWM to its pincontrol, and documents what
the outputs are on the XU3
- switches the LEDs that are on PWM outputs to use PWM
rather than GPIO.
The main effect is that the brightness of the LEDs can be controlled, and
user-mode fan control is enabled via /sys/class/pwm
