[MIPS] Make timer interrupt frequency configurable from kconfig.

Browse source 
Make HZ configurable.  DECSTATION can select 128/256/1024 HZ, JAZZ can
only select 100 HZ, others can select 100/128/250/256/1000/1024 HZ if
not explicitly specified).  Also remove all mach-xxx/param.h files and
update all defconfigs according to current HZ value.
