arm: zynq: Removed CONFIG_SYS_MALLOC_LEN for mini configuration
This patch removed CONFIG_SYS_MALLOC_LEN from the header file as it
was already handled through Kconfig. During nand write operation,
CONFIG_SYS_MALLOC_LEN defined in header file was giving End of Memory
error.
nand write is working fine with the CONFIG_SYS_MALLOC_LEN defined
in cse_nand defconfig.

arm64: zynqmp: mini-emmc: Added clock configuration in the device tree
This patch added clock configuration for mini emmc in the
device tree and enabled CONFIG_MMC_SDHCI_ZYNQ in defconfig.
Without CONFIG_MMC_SDHCI_ZYNQ, the device was failed to
register. Without this clk configuration, mmc device was
failed to get clk. CONFIG_DOS_PARTITION will be enabled
through Kconfig and hence removed from header file.
After adding all these changes, emmc is working fine.
This patch fixes the issue with qspi_write_twice by properly
calculating the sizes, offsets and by erasing the region
before writing to it. This also removes unnecessary
erase block. Thsi fixes the issue of CRC failures in
qspi_write_twice.
