wifi: rtw88: 8703b: Fix RX/TX issues

Fix 3 typos in 8703b driver. 2 typos in calibration routines are not
fatal and do not seem to have any impact, just fix them to match vendor
driver.

However the last one in rtw8703b_set_channel_bb() clears too many bits
in REG_OFDM0_TX_PSD_NOISE, causing TX and RX issues (neither rate goes
above MCS0-MCS1). Vendor driver clears only 2 most significant bits.

With the last typo fixed, the driver is able to reach MCS7 on Pinebook
