FW Download procedure can block on del_timer_sync because the
timer is not running. This patch check that timer is scheduled
before cancelling it.

Reset GPIO shall be freed by the driver since the device used
in devm_ calls can be still valid on unregister.
If user removes the module and inserts it again, the devm_gpio_request
will fail because the underlying physical device (e.g i2c) was not
removed so the device management won't have freed the gpio.

The newly added nfcmrvl_spi driver uses the spi_nci
infrastructure, but does not have a Kconfig dependency on
that, so we can get a link-time error:
drivers/built-in.o: In function `nfcmrvl_spi_nci_send':
(.text+0x1428dc): undefined reference to `nci_spi_send'
drivers/built-in.o: In function `nfcmrvl_spi_probe':
(.text+0x142a24): undefined reference to `nci_spi_allocate_spi'
drivers/built-in.o: In function `nfcmrvl_spi_int_irq_thread_fn':
(.text+0x142abc): undefined reference to `nci_spi_read'
This clarifies the dependency.

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.

As I understand it, the core nfcmrvl module is useless without
either the USB or the UART access module. So hide NFC_MRVL and select
it automatically if either NFC_MRVL_USB or NFC_MRVL_UART is selected.
This avoids presenting NFC_MRVL when neither NFC_MRVL_USB nor
NFC_MRVL_UART can be selected.

These settings are related to a specific integration that requires
the firmware to drive some GPIOs for external RF coexistency.
Since this is really linked to specific hardware integration let's

Add missing terminating newlines to nfc_info and nfc_err

o remove unnecessary OOM messages as there's a generic dump_stack()
o realign arguments

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.
