machine.SDCard doesn't release the SDSPI when deleted
port-esp32
Note that sdspi_host_init_slot gets called on creation
https://github.com/micropython/micropython/blob/246f3f640dd635f67269bfdbebe23408f77cd2b0/ports/esp32/machine_sdcard.c#L227
but on deletion sdspi_host_deinit doesn't get called (only the mmc gets deinit)
https://github.com/micropython/micropython/blob/246f3f640dd635f67269bfdbebe23408f77cd2b0/ports/esp32/machine_sdcard.c#L261
As the SDCard object acquires it but never releases it, this bug prevents sharing the SPI with other modules.

micropython 1.15 esp32 reboot at SD deinit
port-esp32
After unmounting SD card I need to release it's pins (to input or hi-z)
for this I want to deinit SD card and set pins to input, but at deinit
ESP32 reboots. esp32spiram-idf3-20210202-v1.14.bin doesn't
reboot, but idf4 versions reboot.
