- Configures `PLL2->PFD0` with **198MHz** as base clock of
`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!
SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.
