Implement firmware download protocol for Marvell NFC controllers.
This protocol is based on NCI frames that's why parts of its
implementation use some NCI generic functions.

PB_BAIL_OUT parameter as to be set to one. This is needed because
digital protocol 1.0 is used in combination with ISO15693 protocol.

Low level driver can specify a GPIO that will be used to reset
the chip. Thanks to this the driver can ensure the state of the
device at init.

Marvell nfc device provides support for external coexistance
control. It allows Device Host to inhibit the NFCC from polling
when required by asserting a GPIO pin. A second pin allows the
DH to have feedback on the current NFCC state.
The required configuration for this feature is done in setup
handler.
