video: exynos_dp: Make dp_regs global

Browse Source 
dp_regs variable was redundantly defined across all the functions in
the driver even though it contains just the same address. We make it
global and initialize it once using exynos_dp_set_base_addr().
>From then on, other funtions can use the address stored in the global variable.
