clk: pxa1928: Move number of clocks to driver source

The number of clocks should not be in the dt binding as it is not used
by the respective device tree and thus needlessly bloats the ABI.

Move this number of clocks into the driver source.

clk: mmp: add PXA1928 clock support

Add initial clock support for Marvell PXA1928. The PXA1928 is a mobile
SOC and is similar to other MMP/PXA series of SOCs, so a lot of the
existing infrastructure is reused here.

Currently the PLLs are just fixed clocks, and not all leaf clocks are
implemented.
