Christophe Leroy 106fc089cc gpio: max7301: fix driver for use with CONFIG_VMAP_STACK 
commit abf221d2f5 upstream.

spi_read() and spi_write() require DMA-safe memory. When
CONFIG_VMAP_STACK is selected, those functions cannot be used
with buffers on stack.

This patch replaces calls to spi_read() and spi_write() by
spi_write_then_read() which doesn't require DMA-safe buffers.

Fixes: 0c36ec3147 ("gpio: gpio driver for max7301 SPI GPIO expander")
