[PATCH 5.2 186/215] fpga-manager: altera-ps-spi: Fix build error

[Greg Kroah-Hartman]

From: YueHaibing <yuehaib...@huawei.com>

commit 3d139703d397f6281368047ba7ad1c8bf95aa8ab upstream.

If BITREVERSE is m and FPGA_MGR_ALTERA_PS_SPI is y,
build fails:

drivers/fpga/altera-ps-spi.o: In function `altera_ps_write':
altera-ps-spi.c:(.text+0x4ec): undefined reference to `byte_rev_table'

Select BITREVERSE to fix this.
