pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init

Browse source

Regmap initialization triggers regcache_maple_populate() which attempts
SPI read to populate cache. SPI read requires mcp->dev and mcp->addr to
be set, without them, NULL pointer dereference occurs during probe.

Move initialization before mcp23s08_spi_regmap_init() call.
