[PATCH 013/379][SRU][OEM-5.6] Bluetooth: hci_qca: Optimized code while enabling clocks for BT SOC

[You-Sheng Yang]

From: Venkata Lakshmi Narayana Gubba <gubbaven at codeaurora.org>

BugLink: https://bugs.launchpad.net/bugs/1879633

* Directly passing clock pointer to clock code without checking for NULL
  as clock code takes care of it
* Removed the comment which was not necessary
* Updated code for return in qca_regulator_enable()
