Enable pinctrl driver for usdhc. USDHC driver uses custom pinctrl states
for fast, slow, and medium signal frequencies, as well as pin pull for
SD detection.

USDHC driver did not pass disk test (failed during multiple writes). Add
logic to wait for the SD card to be idle before reading new data, so
that the test will pass. Also, add logic to reject OOB reads and writes
to the disk.

RT11xx USDHC lacks some watermarking features that RT10xx SOCs include.
Place #ifdef guards around these features.

The function usdhc_board_access_init was returning a non-zero
value as the variable "ret" is also used to store the GPIO
level for card-detect.

1. Do not throw an error when FSL_FEATURE_USDHC_HAS_HS400_MODE
is defined
2. Add support for the case when the card detect is handled
by the USDHC module

When 1.8V is disabled, sdhc can only
communicate at low speed. But this can
save the external circuit for switching
between 3.3V and 1.8V, which is very
practical in costdown scenarios.

The SD Card below Physical Layer 1.10 does not support CMD6.
When usdhc_sd_init is executed, it will fail to exit due to
execution of CMD6, causing the SD Card to not work normally.
For different SD Card Physical Layer specifications,
the following modifications have been made:
Version 1.10 and above support CMD6.
Version 3.0 and above support CMD6 Group 3 (driver strength
and current limit) .

The files disk_access_usdhc.c, disk_access_spi_sdhc.c,
disk_access_stm32_sdmmc.c, disk_access_ram.c and
disk_access_flash.c are actually drivers for block devices and SD/MMC
controllers. This patch moves this drivers to drivers/disk and
reworks the configuration so that the drivers are selected when
the corresponding node is enabled.
