[Buildroot] [PATCH v5 8/9] package/nxp/qoriq-rcw: introduce BR2_PACKAGE_HOST_QORIQ_RCW_BOOT_MODE for boot mode

[Changming Huang <jerry.huang@nxp.com>]

Introduce BR2_PACKAGE_HOST_QORIQ_RCW_BOOT_MODE for the boot mode.
Because the RCW binary can be stored in different media, for example:
sd - RCW locate in SD card, boot the board from SD card
emmc - RCW locate in eMMC chip, boot the board from eMMC chip
qspi - RCW locate in QSPI flash, boot the board from QSPI flash
flexspi_nor - RCW locate in flexSPI, boot the board from flexSPI Nor/Nand flash
