ARM: S5PV210: Remove usage of clk_p83 and add clk_pclk_dsys clock\
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.
