Platform data is used to specify controller hardware specific information
such as the tx/rx fifo level mask and bit offset of rx fifo level. Such
information is not suitable to be supplied from device tree. Instead,
it can be moved into the driver data and removed from platform data.

1. Corrected shift values of I2S and UART clocks (CLK_GATE_IP3), which were
defined incorrectly.
2. Corrected shift values of sclk_audio, uclk1, sclk_fimd, sclk_mmc,
sclk_spi, sclk_pwm, which had duplicated .enable/.ctrlbit with their
twins defined in struct clk init_clocks_disable[] and struct clk
init_clocks[]. We've changed their .enable/.ctrlbit to use CLK_SRC_MASK
register to avoid the duplicated clock problem described below.
NOTE: Duplicated Clock Problem
Please note that each clock definition should access different control
register; otherwise, the system may suffer lockups. For example, if we
have two clock definitions "a" and "b" which access the same register
(and the shift value). Then, when we do:
module A
clk = clk_get("a");
clk->clk_enable(clk);
module B (context switch)
clk = clk_get("b");
clk->clk_enable(clk);
do something with clk.
clk->clk_disable(clk);
module A (context switch)
do something with clk
* At this point, the system may hang.
Therefore, there should be no clock definitions with the same contol
register/shift. If we need to create "aliases", then, creating child
clocks sharing the clock should be fine.
3. Corrected other sclk_* shift values and access registers.

The clk_p83 clock, which is the PCLK clock for PSYS domain, is of
type 'struct clk' whereas on S5PV210, this clock is suitable to be
of type clksrc_clk clock (since it has a clock divider). So this
patch replaces the 'struct clk' type clock to 'struct clksrc_clk'
type clock for the PCLK PSYS clock.
This patch modifies the following.
1. Removes definitions and usage of 'clk_p66' clock.
2. Adds 'clk_pclk_psys' clock which is of type 'struct clksrc_clk'.
3. Replaces all usage of clk_p66 with clk_pclk_psys clock.
4. Adds clk_pclk_psys into list of clocks to be registered.
5. Removes the sys_clks array since it is no longer required.
Also the registration of clocks in sys_clks is also removed.
6. Remove the 'GET_DIV' as it is no longer required.

The clk_p83 clock, which is the PCLK clock for DSYS domain, is of
type 'struct clk' whereas on S5PV210, this clock is suitable to be
of type clksrc_clk clock (since it has a clock divider). So this
patch replaces the 'struct clk' type clock to 'struct clksrc_clk'
type clock for the PCLK DSYS clock.
This patch modifies the following.
1. Remove definitions and usage of 'clk_p83' clock.
2. Adds 'clk_pclk_dsys' clock which is of type 'struct clksrc_clk'.
3. Replace all usage of clk_p83 with clk_pclk_dsys clock.
4. Adds clk_pclk_dsys into list of clocks to be registered.

The clk_h100 clock represents the IMEM clock for the MSYS domain.
This clock rate of this clock is always half of the hclk_msys clock.
There is an issue when getting the clock rate of the clk_h100 clock
(clock get_rate hclk_h100 always returns clock rate that is equal to
the hclk_msys clock rate).
This patch modifies the following.
1. Moves the definition of the clk_h100 clock into the 'init_clocks'
list with the appropriate parent, ctrlbit, enable and ops fields.
2. The name of the clock is changed from 'clk_h100' to 'hclk_imem'
to represent more clearly that is represents the IMEM clock in
the MSYS domain.
3. The function to get the clock rate of the hclk_imem clock is added.
