board: phytec: phycore-imx91-93: Add phyCORE-i.MX91 support

Browse Source 
As the PHYTEC phyCORE-i.MX91 [1] is just another variant of the existing
PHYTEC phyCORE-i.MX93 SoM but with i.MX91 SoC populated instead, add it
to the existing board-code "phycore_imx93", and rename that board to
"phycore_imx91_93" to reflect the dual SoCs support. While at it, also
rename and change common files accordingly. This way i.MX91 and i.MX93
SoC variants of the phyCORE SoM share most of the code and documentation
without duplication, while maintaining own device-tree and defconfigs
for each CPU variant.

Supported features:
 - 1GB LPDDR4 RAM
 - Debug UART
 - EEPROM
 - eMMC
 - Ethernet
 - SD-card
 - USB

===============
phyCORE-i.MX 91/93
==================
U-Boot for the phyCORE-i.MX 93.
U-Boot for the phyCORE-i.MX 91/93. Both SoC variants, that is i.MX 91 and i.MX 93,
are supported by same board code, however each variant uses different defconfig
and ATF/ELE firmware blobs. Please follow the correct steps for the populated SoC.
