To reduce the duplicated code, add a new file to accommodate
the peripheral's and system's clock handle code, shared with
the SoCs with different ARM core.

Some peripherals may need a second clock source that may be different
from the system clock. This second clock is the generated clock (GCK)
and is managed by the PMC via PMC_PCR.
For simplicity, the clock source of the GCK is fixed to PLLA_CLK.
