CLOCKSOURCE: Add Pistachio clocksource-only driver
The Pistachio SoC provides four general purpose timers, and allow
to implement a clocksource driver.
This driver can be used as a replacement for the MIPS GIC and MIPS R4K
clocksources and sched clocks, which are clocked from the CPU clock.
Given the general purpose timers are clocked from an independent clock,
this new clocksource driver will be useful to introduce CPUFreq support
for Pistachio machines.
