Neil Armstrong 9f7406d6b5 media: platform: ao-cec-g12a: disable regmap fast_io for cec bus regmap 
With fast_io enabled, spinlock_irq is used for read/write operations,
thus leading to :
BUG: sleeping function called from invalid context at [snip]/ao-cec-g12a.c:379
 in_atomic(): 1, irqs_disabled(): 128, pid: 1451, name: irq/14-ff800280
[snip]

Simply remove fast_io to use mutexes instead.
