328fc9b298 pmdomain: amlogic: remove obsolete vpu domain driver 
meson-gx-pwrc-vpu has been superseded by meson-ee-pwrc since
commit 53773f2dfd ("soc: amlogic: meson-ee-pwrc: add support for the Meson GX SoCs"),
so v5.8.

This driver is obsolete and no longer used or tested.
There is no reason to keep it around so remove it.

3324a8196a pmdomain: amlogic: Constify struct meson_secure_pwrc_domain_desc 
'struct meson_secure_pwrc_domain_desc' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
   4909	   4072	      0	   8981	   2315	drivers/pmdomain/amlogic/meson-secure-pwrc.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
   8605	    392	      0	   8997	   2325	drivers/pmdomain/amlogic/meson-secure-pwrc.o

cc647e931a pmdomain: amlogic: add missing MODULE_DESCRIPTION() macros 
On x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pmdomain/amlogic/meson-gx-pwrc-vpu.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/pmdomain/amlogic/meson-ee-pwrc.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes meson-secure-pwrc.c which, although it did not produce a
warning with the x86 allmodconfig configuration, may cause this
warning with other configurations where CONFIG_MESON_SM is enabled.

e2ad626f8f pmdomain: Rename the genpd subsystem to pmdomain 
It has been pointed out that naming a subsystem "genpd" isn't very
self-explanatory and the acronym itself that means Generic PM Domain, is
known only by a limited group of people.

In a way to improve the situation, let's rename the subsystem to pmdomain,
which ideally should indicate that this is about so called Power Domains or
"PM domains" as we often also use within the Linux Kernel terminology.
