## Summary This implements the missing callback hooks nrf52_spi0/1/2/3register that are usually used with mmcsd for card detection. This also stubs out the missing spi trigger function which is not used on this platform. ## Impact SD Card detection with SPI can now be used on the nRF52 platform. ## Testing The card detect was tested with the nRF52-feather board and a modified KeyBoard FeatherWing. Here is an example of it running where I started with the SD Card in (not shown) and then removed it and inserted it back in. ``` NuttShell (NSH) NuttX-9.1.0 nsh> kb_card_state: Detected Card Change: Removed. mmcsd_mediachanged: WARNING: No card present kb_card_state: Detected Card Change: Inserted. mmcsd_mediainitialize: Send CMD0 mmcsd_sendcmd: CMD0[00000000] R1=01 mmcsd_mediainitialize: Card is in IDLE state mmcsd_mediainitialize: Send CMD8 mmcsd_sendcmd: CMD8[000001aa] R1=01 R7=000001aa mmcsd_mediainitialize: 0.
