S5PV210 CPUFREQ Initial Support.

This is a series of patches to enable CPUFREQ for S5PV210.

Although this works without PMIC's DVS support, it is not
as effective without DVS support as supposed. AVS is not
supported in this version.

At the patch revision v6, the following patches are updated from v5.
- 1/7: ARM: S5PV210: Allow to probe EVT revision number
	* Removed EVT1-Fused and related functions
	* Renamed evt related functions.
- 3/7: ARM: S5P: Added default pll values for APLL 800/100MHz
	* Corrected style.
- 7/7: ARM: S5PV210: Initial CPUFREQ Support
	* Following the renamed evt-related functions at 1/7 patch.

At the patch revision v5, the following patches are updated from v4.
- 1/7: ARM: S5PV210: Allow to probe EVT revision number
	* Renamed revision check function
	* Revise revision check function so that it does not access
	board-specific information
	* Chip-ID is used to identify some of EVT revisions.
	* Added "s5pv210_revision_or_later()" function
- 6/7: ARM: S5PV210: clock registers (CLK_DIV/SRC/STAT)
	* Added entry infromation for G3D/G2D/MFC of the register
	S5P_CLK_[DIV|MUX]_STAT[0|1]. These entries are accessed
	multiple times at /arch/arm/mach-s5pv210/cpufreq.c.
- 7/7: ARM: S5PV210: Initial CPUFREQ Support
	* Remove unnecessary USE_FREQ_TABLE
	* Renamed functions in cpufreq.c
	* Initialization of s5pv210_cpufreq_target (previously,
	s5pv210_target) is revised (initilization --> first_run)
	* "workaround" --> "revision"
	* CLK_*_STATx register entries use macros: they are used
	multiple times.
