0a0f0e737b clk: at91: Add support for sam9x60 USB clock
Implement sam9x60 USB clock driver. This clock has
three parents: PLLA, UPLL and MAINXTAL. The driver is
aware of the three possible parents with the help of the
two mux tables provied to the driver during the registration
of the clock.

Move clock code to compat.c to allow switching to CCF
without mixing CCF code with non CCF code. This prepares the

fed0509c92 clk: at91: add PLLADIV driver
As said in the SAMA5D2 datasheet, the PLLA clock must be divided
by 2 by writing the PLLADIV2 bit in PMC_MCKR, if the ratio between
PCK and MCK is 3 (MDIV = 3). This is the purpose of the driver.
