powerpc/sysdev: implement FSL GTM support
GTM stands for General-purpose Timers Module and able to generate timer{1,2,3,4} interrupts. These timers are used by the drivers that need time precise interrupts (like for USB transactions scheduling for the Freescale USB Host controller as found in some QE and CPM chips), or these timers could be used as wakeup events from the CPU deep-sleep mode. Things unimplemented: 1. Cascaded (32 bit) timers (1-2, 3-4). This is straightforward to implement when needed, two timers should be marked as "requested" and configured as appropriate. 2. Super-cascaded (64 bit) timers (1-2-3-4). This is also straightforward to implement when needed, all timers should be marked as "requested" and configured as appropriate.
