Adds code to detect AM43xx HS EVMS - the string in the I2C EEPROM for HS EVMs differs from GP EVMs. Adds code to for evm detection, regardless of whether the evm is for GP or HS parts, and updates board init to use that. Modifies findfdt command to pick up am437x-gp-evm.dtb for the HS EVMs also, as the boards are similar except for some security specific changes around power supply and enclosure protection.
