[MIPS] Alchemy: don't unmask timer IRQ early
Defer the unmasking of the count/compare interrupt (IRQ5) till the
clockevent driver initialization:
- only enable the cascaded IRQs 0 thru 4 in arch_init_irq(); kill the
ALLINTS macro -- this change is blessed by AMD as I saw it in their own
patch; :-)
- do not force IRQ5 enabled in plat_time_init() if PM is enabled and there's
no 32 KHz crystal.
Update the copyrights (taking into account my prior changes), also removing
Pete Popov's old email...
