regmap: Fix possible sleep-in-atomic in regmap_bulk_write()

regmap deploys the spinlock for the protection when set up in fast_io
mode.  This may lead to sleep-in-atomic by memory allocation with
GFP_KERNEL in regmap_bulk_write().  This patch fixes it by moving the
allocation out of the lock.

[Fix excessively large locked region -- broonie]
