Use the appropriate fdtdec_setup_mem_size_base and
fdtdec_setup_bank_size calls in dram_init and dram_bank_init to pull
these values from DT, where they are already available, instead of
hardcoding them.

Call dram_init_banksize() from spl_board_init() otherwise TFTP download
fails due to lmb_get_free_size() not able to find unreserved region due
to lack of DRAM size info. Required to support Ethernet boot on AM64x.

Fix the dr_mode in the U-Boot device tree blob, by reading the mode field
from the USB Boot Configuration fields. The dr_mode will only be fixed when
booting from USB.

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.

Add a proper comment to simple_strtoul() while we are here.

I2C EEPROM data contains the board name and its revision.
Add support for:
- Reading EEPROM data and store a copy at end of SRAM
- Updating env variable with relevant board info
- Printing board info during boot.
