To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols.  This usually means that no global variables can
be marked static unless they're also const.

Let's remove the static qualifier from current offenders, or turn them
into const variables when possible.  Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

This patch adds support HRT for machines of S5P64X0 and S5PV210.
Basically, PWM Timer3 is used for clockevent and PWM Timer4 is
used for clocksource. Since PWM Timer3 is used for other purpose,
PWM Timer2 is used on SMDKV210.

This patch modifies the number of total GPIO lines for Bank F
for Samsung S5P6440 and S5P6450 SoCs from 2 to 16.
This is necessary as the GPIO lines from 0 to 13 are reserved
and only lines 14 and 15 are used. As during initialization,
the line number starts at 0, putting 2 does not solve the
intended purpose.

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.
