clocksource/drivers/timer-microchip-pit64b: Add Microchip PIT64B support
Add driver for Microchip PIT64B timer. Timer could be used in continuous mode or oneshot mode. The hardware has 2x32 bit registers for period emulating a 64 bit timer. The LSB_PR and MSB_PR registers are used to set the period value (compare value). TLSB and TMSB keeps the current value of the counter. After a compare the TLSB and TMSB register resets. The driver uses PIT64B timer for clocksource or clockevent. First requested timer would be registered as clockevent, second one would be registered as clocksource. Individual PIT64B hardware resources were used for clocksource and clockevent to be able to support high resolution timers with this hardware implementation.
