staging: rtl8723bs: remove wrapper rtw_hal_read_chip_version()

Remove rtw_hal_read_chip_version() function, as it's just a wrapper
that calls rtl8723b_read_chip_version() directly. Replace all its calls
to the rtl8723b_read_chip_version(). This will remove an extra level of
abstraction and simplify the code.
