rt2x00: add support for MT7620

From: Roman Yeryomin <[email protected]>

Basic support for MT7620 built-in wireless radio was added to OpenWrt in r41441. It has seen some heavy cleaning and refactoring since in order to match the Kernel's code quality standards.

---
v3: rebase on corrected rt2800.h
v2: added RT6352 instead of checking against RF7620
cleaned up rf_vals_7620 and channel switching cargo-cult ported bandwidth filter calibration (feels fishy, but works)
fixed some typos in the comments
