Subject: [PATCH v4 1/5] clk: qcom: clk_mem_branch: add enable mask and
 invert flags

Introduce mem_enable_mask and mem_enable_invert in clk_mem_branch to
describe memory gating implementations that use a separate mask and/or
inverted enable logic. This documents hardware behavior in data instead
of code and will be used by upcoming platform descriptions.
