[PATCH v4 0/1] gpio: add driver for Mellanox BlueField GPIO controller

Changes since v3
- the naming scheme has been fixed to remove double underscores and use
standard variable names
- the locking has been updated to protect the entire read/modify
operations.

Regarding the suggested use of the generic MMIO library, I noticed that
bgpio_init only allows for either dirin or dirout to be set, never both.
But since our controller has 2 separate registers, using bgpio_init
might not be possible here.
