The clk_h_low clock is of type 'struct clk' whereas on S5P6440,
the hclk_low clock is more suitable to be of type 'struct clksrc_clk'
(since hclk_low clock is derived from a choice of clock sources and
then divided by a divisor).
This patch modifies the following.
1. Removes the definition and usage of clk_h_clk clock.
2. Adds the clk_hclk_low clock of type 'struct clksrc_clk' clock.
3. Adds clk_hclk_low to the list of system clocks.
4. The clock rate of hclk_low is derived from the clk_hclk_low clock.

The clk_p clock is of type 'struct clk' whereas on S5P6440,
the pclk is more suitable to be of type 'struct clksrc_clk'
(since pclk clock is divided version of hclk).
This patch modifies the following.
1. Adds the 'clk_pclk' clock which is of type 'struct clksrc_clk'.
2. Adds clk_pclk into the list of sysclks.
3. The clock rate 'pclk' is modified to be derived from clk_pclk.

The clk_h clock is of type 'struct clk' whereas on S5P6440,
the hclk is more suitable to be of type 'struct clksrc_clk'
(since hclk clock is divided version of armclk)
This patch modifies the following.
1. Adds the 'clk_hclk' clock which is of type 'struct clksrc_clk'.
2. Removes all references to the clk_h clock.
3. Addes clk_hclk into the list of sysclks.
4. The clock rate 'hclk' is modified to be derived from clk_hclk.

The clk_arm clock is of type 'struct clk' whereas on S5P6440,
the arm clock is more suitable to be of type 'struct clksrc_clk'
(since arm clock is divided version of apll clock).
This patch modifies the following.
1. Removes the usage of clk_arm clock (defined in plat-s5p) and
defines the new clock 'clk_armclk' of type 'struct clksrc_clk'.
2. Rearranges the assignment of clock rate for the fout_a/m/epll
clocks. This will help in calculating the clock rate of fclk
from clk_armclk clock and setup the clock rate for fout_m/epll
for subsequent patches which depend on it.
3. Modifies the clock rate calculation of fclk to be based on
the newly added clk_armclk clock.

This patch modifies the following.
1. Modifies the dout_mpll clock type as clksrc_clk clock type.
This modification allows the use of common clock code in
managing the dout_mpll clock (which otherwise would need
custom defined functions such as s5p6440_clk_doutmpll_get_rate).
2. s5p6440_clk_doutmpll_get_rate function is removed as it is
no longer needed.

This patch modifies the following.
1. Registers the mout_apll clksrc_clk clock.
2. The mout_mpll and mout_epll were registered as 'struct clk'
types and then their parents were setup using the s3c_set_clksrc
function. This patch reduces the two steps into one by registering
the mout_mpll and mout_epll clocks using the s3c_register_clksrc
function.
3. As per point 2 above, the init_parents array is no longer required.
So the mout clocks are now put together in a new array named 'sysclks'.
The sysclks array will list the system level clocks and more
clocks will be added to it in the subsequent patches.

Commit 4e6d488af3 either missed out the
following machine files or somehow managed to clash between merges.
Fixup the three files missing the second parameter to addruart macro
to allow them to build.
Fixes the following warnings in arch/arm/kernel/debug.c:

Move the include/mach files out of plat-s3c and into the relevant

1. Moved common memory map definitions for S5P such as S5P_VA_XXX
into plat-s5p/include/mach/map-s5p.h from mach-s5p6440/include/mach.
2. Removed unnecessary definitions in the map.h and irq.c
3. Removed the unnecessary support for unaligned UART address
4. Renamed S5P_VA_VICx definitions as VA_VICx
5. Moved the definitons of VIC_BASE to plat-s5p/include/plat/irqs.h

The s5p6440-clock.c and s5p6440-init.c code in the plat-s5p is specific to
s5p6440 SoC based systems. So these files are being moved to the machine
directory of s5p6440. And these files are renamed in the machine directory.
