Add SPI NOR driver for Sophgo, including read, write operations.
This driver is only suitable for NOR flash.
If there is a next patchset, please also replace "Sopgho" with "SG2044" in the cover letter, including the email title.

Changes in v2:

Fixed following issues as per comments from Yixun Lan, Chen Wang, Inochi Amaoto, thanks.

I feel like you left out Rob, and you also left out his signature in the first patch ;)


- Replaced "sophgo" to "sg2044" to avoid conflicts with other drivers.
- Improve driver code:
- Improve coding style.
- Removed the [PATCH 3/3] in previous submission that based on the baseline not submitted.
- Added error handler to destroy mutex if probe fail.
