[ARM] OMAP3 clock: convert dpll_data.idlest_bit to idlest_mask
Convert struct dpll_data.idlest_bit field to idlest_mask. Needed since OMAP2 uses two bits for DPLL IDLEST rather than one. While here, add the missing idlest_* fields for DPLL3. linux-omap source commits are 25bab0f176b0a97be18a1b38153f266c3a155784 and b0f7fd17db2aaf8e6e9a2732ae3f4de0874db01c.
