Subject: [PATCH] spi: sprd: Fix the incorrect SPI register
Git-commit: 5e9c5236b7b86779b53b762f7e66240c3f18314b
Patch-mainline: v5.5-rc3
References: git-fixes

The original code used an incorrect SPI register to initialize the SPI
controller in sprd_spi_init_hw(), thus fix it.

Fixes: e7d973a31c24 ("spi: sprd: Add SPI driver for Spreadtrum SC9860")
