Subject: [PATCH 1/4] mtd: rawnand: qcom: cleanup qcom_nandc driver
Perform a global cleanup of the Qualcomm NAND
controller driver with the following improvements:
- Remove register value indirection API
- Remove set_reg() API
- Convert read_loc_first & read_loc_last macro to functions
- Rename multiple variables
