[PATCH 34/40] [SRU][Lunar/OEM-6.1] wifi: rtw89: 8852b: add chip_ops related to RF calibration

[Koba Ko]

From: Ping-Ke Shih <pkshih at realtek.com>

BugLink: https://bugs.launchpad.net/bugs/2002601

Since RF calibrations are added, add chip_ops to call them. These chip_ops
include initial, full calibration, configuration when switching band and
scanning, and track work in period of 2 seconds.
