Sure, I can do that. By any chance, do you have a suggestion for the name of the
new enum value to be used in the clk_alpha_pll_regs array?

CLK_ALPHA_PLL_TYPE_HUAYRA_IPQ seems too generic, and it would be a bit
misleading using that for MSM8996 CBF.

CLK_ALPHA_PLL_TYPE_HUAYRA_IPQ6018_A53 is quite long and it is also misleading.

Maybe we could use CLK_ALPHA_PLL_TYPE_IPQ6018_A53 which is short and unique
enough and we could add an alias for that like CLK_ALPHA_PLL_TYPE_MSM8996_CBF or
something similar.
