soc: qcom: geni-se: Use HW PROG_RAM_DEPTH to validate firmware size

Browse source

The hardcoded MAX_GENI_CFG_RAMn_CNT limit is not accurate for all SoCs:
some targets have less CFG RAM than the constant implies, while others
like QCS615 need more entries than the old limit of 455 allowed, causing
valid firmware to be rejected at load time.

Rather than hardcoding a constant, read PROG_RAM_DEPTH from SE_HW_PARAM_2
at runtime to get the actual CFG RAM depth of the hardware instance and
use that as the upper bound for firmware size validation.
