John Garry 3bc45af81d scsi: hisi_sas: Add v2 hw support for different refclk
The hip06 D03 and hip07 D05 boards have different reference clock
frequencies for the SAS controller.

Register PHY_CTRL needs to be programmed differently according to this
frequency, so add support for this.

The default register setting in PHY_CTRL is for 50MHz, so only update
this register when the refclk frequency is 66MHz.

For ACPI we expect the _RST handler to set the correct value for
PHY_CTRL (we're forced to take different approach for DT and ACPI as
ACPI does not support fixed-clock device).
