This allows us to use smp_cross_call() to trigger a number of different
software generated interrupts, rather than combining them all on one
SGI. Recover the SGI number via do_IPI.

S5P Samsung SoCs has a EPLL to support various PLL clock sources for other
H/W blocks. Until now, to control EPLL, each of SoCs make their own functions
in 'mach-s5pxxx/clock.c'. But some of functions, 'xxx_epll_get_rate()' and
'xxx_epll_enable()', are exactly same in all S5P SoCs, so this patch move
these duplicated codes to common EPLL functions that use platform wide.

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.
