drm/amd/display: Fix Silence Conversion Warnings in Dmub

Browse source

Fix Conversion that might result in a loss of data  warnings in dmub/src/:

- dmub_dcn20/31/32/35/42/60/401.c: Add ASSERT(value <= 0xFF) and
  explicit (uint8_t) cast when storing REG_GET results into uint8_t
  debug struct fields. Add != 0 for bool assignments from uint32_t
  bitfield reads.
- dmub_reg.c: Cast va_arg shift value to uint8_t with ASSERT guard
  before passing to set_reg_field_value_masks().
- dmub_srv.c: Widen num_pending to uint64_t to match uint64_t
  arithmetic; use != 0 for bool assignments from unsigned expressions.

No functional change intended.
