Subject: [PATCH wireless-next 10/11] wifi: rtlwifi: rtl8723_common: using calculate_bit_shift()

Using calculate_bit_shift() to replace rtl8723_phy_calculate_bit_shift().
And fix the undefined bitwise shift behavior problem.

Fixes: 0a168b48cdf7 ("rtlwifi: rtl8723ae: rtl8723-common: Create new driver for common code")
