bafa6f591b am33xx: Unused get_board_rev function removal
All am33xx device tree are using device-tree, so get_board_rev is never actually
called. Thus, we can get rid of it to make the code easier to maintain.

52d848695c am335x: make get_board_rev() function weak
Current get_board_rev() function returns a hard coded value which is
obviously incorrect for the majority of boards.
Allow boards to provide a correct implementation by making this
function weak.
In addition open code the trivial and useless BOARD_REV_ID define and
adjust the comment.

21254713d3 am33xx: report silicon revision instead of code
As revision code 1 is for silicon revision 2.0, it is easily confused with
silicon revision 1.0.

Device type report also reworked in same style.

9721027aae am335x_evm: am33xx_spl_board_init function and scale core frequency
Add a am33xx_spl_board_init (and enable the PMICs) that we may see,
depending on the board we are running on.  In all cases, we see if we
can rely on the efuse_sma register to tell us the maximum speed.  In the
case of Beaglebone White, we need to make sure we are on AC power, and
are on later than rev A1, and then we can ramp up to the PG1.0 maximum
of 720Mhz.  In the case of Beaglebone Black, we are either on PG2.0 that
supports 1GHz or PG2.1.  As PG2.0 may or may not have efuse_sma set, we
cannot rely on this probe.  In the case of the GP EVM, EVM SK and IDK we
need to rely on the efuse_sma if we are on PG2.1, and the defaults for
PG1.0/2.0.

244044e151 ARM: AM33XX: Fix typo that causes an AM duplication in CPU name.
Just fix a typo displaying the CPU info. With CONFIG_DISPLAY_INFO we see
something like AMAM335X-GP rev 0 instead of AM335X-GP rev 0.
