drm/amd/pm: Fix pp_entries_max() bios check

Browse source

Commit 055a40c32f ("drm/amd/pm: Use uploaded size for legacy custom
PPTable") changed pp_dpm_set_pp_table() to kmemdup the uploaded buffer
directly and set soft_pp_table_size to the uploaded size.  As a result
soft_pp_table now points to an allocation completely outside adev->bios,
making the pp_end > bios_end check in pp_entries_max() likely true for
custom PP tables — returning 0 and breaking PP table overrides via sysfs.
