misc: microchip: pci1xxxx: Fix missing spin_lock_init()
The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.
Fixes: 7d3e4d807df2 ("misc: microchip: pci1xxxx: load gpio driver for the gpio controller auxiliary device enumerated by the auxiliary bus driver.")
