drm/amd/powerplay: replace smu->table_count with SMU_TABLE_COUNT in smu (v2)

fix bellow patch issue:
drm/amd/powerplay: introduce smu table id type to handle the smu table
for each asic
----
"This patch introduces new smu table type, it's to handle the
 different smu table
 defines for each asic with the same smu ip."

before:
use smu->table_count to represent the actual table count in smc firmware
use actual table count to check smu function parameter about smu table
after:
use logic table count "SMU_TABLE_COUNT" to check function parameter
because table id already mapped in smu driver,
and smu function will use logic table id not actual table id to check func parameter.

v2: squash in warning fix
