package/freescale-imx: add i.MX91 and i.MX93 SoC support

Browse Source 
This commit adds i.MX91 and i.MX93 support to Buildroot.
https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-9-processors:IMX9-PROCESSORS

There is no i.MX95 software provided by NXP at the moment that's why
i.MX95 is left behind.

Adapt package firmware-imx for the LPPDR4 firmware binaries. The i.MX91
and i.MX93 only support LPDDR4 and LPDDR4x, but using different binaries
than i.MX8. For simplicity, use a completely separate code path for
i.MX91 and i.MX93, using the symbol
BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW_IMX9. There is only one type of
firmware supported, so there's no need for a choice or for selecting the
version (at least for now).

[Arnout:
 - Remove BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX91A1 option.
 - Re-wrap help text.
 - Introduce BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW_IMX9 instead of
   reusing BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW.
 - Create completely separate instance of
   FIRMWARE_IMX_INSTALL_IMAGE_DDR_FW for
   BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW_IMX9.
 - Drop the training binaries choice for IMX9.
 - Drop the firmware version option for IMX9.
 - Keep options for IMEM and DMEM padding.
