ARM: at91: rm9200: fix usb device clock id
[ Upstream commit 57976762428675f259339385d3324d28ee53ec02 ]
Referring to the datasheet the index 2 is the MCKUDP. When enabled, it
"Enables the automatic disable of the Master Clock of the USB Device
Port when a suspend condition occurs". We fix the index to the real UDP
id which "Enables the 48 MHz clock of the USB Device Port".

clk: at91: clk-programmable: add mux_table option
Add mux table option. This is necessary for IP versions that has
gaps in the range of available clock sources (e.g. SAMA7G5).

clk: at91: allow setting all PMC clock parents via DT
We need to have clocks accessible via phandle to select them
as peripheral clock parent using assigned-clock-parents in DT.
Add support for PLLACK/PLLBCK/AUDIOPLLCK clocks where available.
