firmware: arm_scmi: Fix the clock protocol version for v3.2

The clock protocol version as per the SCMI v3.2 specification is 0x30000.
Enable the v3.0 clock protocol features only when clock protocol version
equals 0x30000.

The previous beta version of the spec had this value set to 0x20001 and
th same value trickled down from the initial development. The version
update were missed in the driver.
