Changes from v1:
 - switched to non-direct links so TRM updates are automatic
 - removed current-speed property from main_uart0
 - removed empty reserved-memory{} node
 - removed serial2 from aliases{} node
 - corrected main_uart0 pinmux

Changes from v2:
 - alphabetized phandles
 - corrected macros and node names for main_uart0 pinmux node

Changes from v3:
 - added and enabled more nodes that have been validated
 - added link to data sheet which is now public

Changes from v4:
 - Corrected Copyright year

Changes from v6:
 - moved thermal-zones{} into the k3-am62l3-evm.dts to allow other
   boards to selec whichever trip points they wish

Changes from v7:
 - enabled &i2c0 to access the eeprom on the board
