As data transfer may starts immediately after i2c eeprom init
completed. Thus i2c eeprom should be initialized after SMU
ready. And i2c data transfer should be prohibited when SMU
down. That is the i2c eeprom fini sequence needs to be
updated also.

The new interface reads the argument in the call to send the message, so
this is no longer needed, and shouldn't be used for concurrency safety
reasons.

Move the responsibility for reading argument registers into the
smu_send_smc_msg* implementations, so that adding a message-sending lock
to protect the SMU registers will result in the lock still being held
when the argument is read.
v2: transition smu_v12_0, it's asics, and vega20

By this, we can avoid to pass in the VRAM address on every table
transferring. That puts extra unnecessary traffics on SMU on
some cases(e.g. polling the amdgpu_pm_info sysfs interface).
V2: document what the driver table is for and how it works

Drop smu_send_smc_msg function from ASIC specify structure.
Reuse smu_send_smc_msg_with_param function for smu_send_smc_msg.
Set paramer to 0 for smu_send_msg function, otherwise it will send
with previous paramer value (Not a certain value).
Materialize msg type for smu send message function definition.

With this cleanup, the APIs from amdgpu_smu.c will map to
ASIC specific ones directly. Those can be shared around
all SMU V11/V12 ASICs will be put in smu_v11_0.c and
smu_v12_0.c respectively.

Those swSMU APIs used internally are moved to smu_internal.h while
others are kept in amdgpu_smu.h.
V2: give a better name smu_internal.h for the place to hold
those internal APIs
