behaviours seen across boards as documented in commit bf6376642fe8
("board: ti: common: board_detect: Fix EEPROM read quirk"). Adding to
the list, we see that there are 2-byte EEPROMs that read properly
with 1-byte addressing with no offset.
For ti_i2c_eeprom_am6_get where eeprom parse operation is dynamic, the
earlier commit d2ab2a2bafd5 ("board: ti: common: board_detect: Fix

ti_i2c_eeprom_get() twice. However this commit along with its former
commit fails on J7 platforms where EEPROM successfully return back the
header on 1-byte addressing and continues to do so until an offset is
introduced. So the second read incorrectly determines the EEPROM as
1-byte addressing.
A more generic solution is introduced here to solve
this issue: 1-byte read without offset and 1-byte read with offset. If
both passes, it follows 1-byte addressing else we proceed with 2-byte

The DM_TIMER uses the whole 64bits with no prescaler,
so the global timer works as a 64-bit PERIPHCLK timer.
CONFIG_SYS_HZ_CLOCK is set as the default PERIPHCLK frequency,
if there is no 'clocks' property in devicetree.
