[PATCH] NFC: nfcmrvl: fix SPI driver dependencies

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.
