clk: qcom: branch: Add mem ops support for branch2 clocks

Add the support for mem ops implementation to handle the sequence of
enable/disable of the memories in ethernet PHY, prior to enable/disable
of the respective clocks, which helps retain the respecive block's
register contents.

clk: qcom: branch: Extend the invert logic for branch2 clocks

Add support to handle the invert logic for branch2 clocks.
Invert branch halt would indicate the clock ON when CLK_OFF
bit is '1' and OFF when CLK_OFF bit is '0'.

clk: qcom: branch: Clean up branch enable registers

Prefix the "branch enable" registers with CBCR_ to be closer to what
they are actually called in Qualcomm terms, use GENMASK instead of
shifting values around and adjust their usage accordingly.

clk: qcom: branch: Add AON clock ops

Some clocks can only be turned on by resetting the block containing
them, provide a clock type that allow us to reference these clocks and
have the client drivers enable and "disable" them.

clk: qcom: clk-branch: Use true and false for boolean values

Return statements in functions returning bool should use true or false
instead of an integer value.

clk: qcom: Add support for BRANCH_HALT_SKIP flag for branch clocks

There could be few clocks where the clock status bit is not
required to be polled as the clock on/off would be controlled
by enabling/disabling external source. Add support for the
same by introducing new flag named as 'BRANCH_HALT_SKIP'.

clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)

Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.

struct clk_hw *E;

-__clk_get_name(E->clk)
+clk_hw_get_name(E)
