The PMC is not only used to drive the clocks but also has some registers
related to other functions. One of those is for example the USB gadget
bias.
Using a syscon allows to properly separate those functions.

The watchdog, the reset controller, the RTC, the real-time timer, the
shutdown controller and the timer counter need the slow clock, add it where
necessary.

The DBGU is not a simple UART and we need to be able to distinguish it from the
other UARTs, in particular to get its address and check the chip id.

Add nodes for the SRAM available on atmel SoCs
For the at91sam9260 and the at91sam9g20, address mirroring is used to create a
single contiguous SRAM range instead of declaring two separate banks.
Also remove leftover TODOs in the sam9g45 file

Having clocks grouped in a subnode is common practice, so move the crystals
under a clocks node for the at91sam9rl SoC and at91sam9rl based boards.

Most of the clock related dt-binding header files are located in
dt-bindings/clock folder. It would be good to keep all the similar
header files at a single location.
