drm/msm/dsi: Add phy configuration for MSM8226
MSM8226 uses a modified PLL lock sequence compared to MSM8974, which is based on the function dsi_pll_enable_seq_m in the msm-3.10 kernel. Worth noting that the msm-3.10 downstream kernel also will try other sequences in case this one doesn't work, but during testing it has shown that the _m sequence succeeds first time also: .pll_enable_seqs[0] = dsi_pll_enable_seq_m, .pll_enable_seqs[1] = dsi_pll_enable_seq_m, .pll_enable_seqs[2] = dsi_pll_enable_seq_d, .pll_enable_seqs[3] = dsi_pll_enable_seq_d, .pll_enable_seqs[4] = dsi_pll_enable_seq_f1, .pll_enable_seqs[5] = dsi_pll_enable_seq_c, .pll_enable_seqs[6] = dsi_pll_enable_seq_e, We may need to expand this in the future.
