[PATCH] gpio: basic_mmio: add missing include of spinlock_types.h

[Jamie Iles <jamie@jamieiles.com>]

include/linux/basic_mmio_gpio.h uses a spinlock_t without including any
of the spinlock headers resulting in this compiler warning.

include/linux/basic_mmio_gpio.h:51:2: error: expected specifier-qualifier-list before 'spinlock_t'

Explicitly include linux/spinlock_types.h to fix it.
