[PATCH] spi: sprd: Fix the incorrect SPI register

[Baolin Wang <baolin.wang7@xxxxxxxxx>]

From: Huanpeng Xin <huanpeng.xin@xxxxxxxxxx>

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")
