[PATCH 49/61] staging: rtl8723bs: remove phy_GetChannelIndexOfTxPowerLimit helper

[Arsenii Pashchenko <ulijg308@gmail.com>]

Remove the tiny single-line helper function
phy_GetChannelIndexOfTxPowerLimit. Inline the arithmetic index
calculation directly into the callers to simplify the code and
reduce runtime call overhead.
