[Why]
DMUB binary is common for both A0 and B0. Hence, driver should
notify FW about the support for DPIA in B0.
[How]
Added dpia_supported bit in dmub_fw_boot_options and will be set
only for B0.
Assign dpia_supported to true before dm_dmub_hw_init
in B0 case.

[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.
[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).
