ArmPkg/ArmScmiDxe: Fix the calculation of RequiredArraySize
As per the SCMI specification, section CLOCK_DESCRIBE_RATES mentions
that the value of num_rates_flags[11:0] in the response must be 3 if
the return format is the triplet. Due to the buggy firmware, this was
not noticed for long time. The firmware is now fixed resulting in
ClockDescribeRates() to fail with "Buffer Too Small" error as the
RequiredArraySize gets miscalculated as 72 instead of 24.
Fix the issue by reusing the logic for both the return format which
must work if num_rates_flags has correct value as expected from the
specification.
