Subject: [RESEND v5 5/6] clk: qcom: lpassaudiocc-sc7280: Merge lpasscc into lpass_aon

Merge lpasscc clocks into lpass_aon clk_regmap structure as they
are using same register space.
Add conditional check for doing lpasscc clock registration only
if regname specified in device tree node.
In existing implementation, lpasscc clocks and lpass_aon clocks are
being registered exclusively and overlapping if both of them are
to be used.
This is required to avoid such overlapping and to register
lpasscc clocks and lpass_aon clocks simultaneously.
