[ Upstream commit 43cdaa1567ad3931fbde438853947d45238cc040 ]
Many i.MX8M SoCs use same 1443X/1416X PLL, such as i.MX8MM, i.MX8MN and later i.MX8M SoCs, moving these PLL definitions to pll14xx driver can save a lot of duplicated code on each platform.
Meanwhile, no need to define PLL clock structure for every module which uses same type of PLL, e.g., audio/video/dram use 1443X PLL, arm/gpu/vpu/sys use 1416X PLL, define 2 PLL clock structure for each group is enough.
