clocksource/drivers/mips-gic-timer: Use correct shift count to extract data
__gic_clocksource_init() extracts the GIC_CONFIG_COUNTBITS field from
read_gic_config() by right shifting the register value. The shift count is
determined by the most significant bit (__fls) of the bitmask which is
wrong as it shifts out the complete bitfield.
Use the least significant bit (__ffs) instead to shift the bitfield down to
bit 0.
