Subject: [PATCH v8 4/5] clk: qcom: lpassaudiocc-sc7280: Merge AHB clocks into lpass_aon

From: Srinivasa Rao Mandadapu <quic_srivasam@...cinc.com>

Merge AHBM and AHBS clocks into lpass_aon clk_regmap structure as they
are using same register space.
Modify AHB clocks explicit registration, from qcom_cc_probe to
com_cc_probe_by_index.
In existing implementation, Q6 AHB clocks and lpass_aon clocks are
being registered exclusively and overlapping if both of them are
to be used. The regmap region used by Q6 AHB clocks is <0x03389000 0x24>
and of lpass_aon clocks is <0x03380000 0x30000>.
This is required to avoid such overlapping and to register
Q6 AHB clocks and lpass_aon clocks simultaneously.
