am43xx: Tune the system to avoid DSS underflows

* This is done by limiting the ARM's bandwidth and setting DSS priority in
the EMIF controller to ensure underflows do not occur.

AM4372 EPOS EVM has 1GB LPDDR2(Part no: MT42L256M32D2LG-25 WT:A)
Adding LPDDR2 init sequence and register details for the same.
Below is the brief description of LPDDR2 init sequence:
-> Configure VTP
-> Configure DDR IO settings
-> Disable initialization and refreshes until EMIF registers are programmed.
-> Program Timing registers
-> Program PHY control and Temp alert and ZQ config registers.
-> Enable initialization and refreshes and configure SDRAM CONFIG register
-> Wait till initialization is complete and the configure MR registers.

ARM: AM43xx: clocks: Update DPLL details

Updating the Multiplier and Dividers value for all DPLLs.
Safest OPP is read from DEV ATTRIBUTE register. Accoring to the value
returned the MPU DPLL is locked.
At different OPPs follwoing are the MPU locked frequencies.
OPP50 300MHz
OPP100 600MHz
OPP120 720MHz
OPPTB 800MHz
OPPNT 1000MHz
According to the latest DM following is the OPP table dependencies:
VDD_CORE VDD_MPU
OPP50 OPP50
OPP50 OPP100
OPP100 OPP50
OPP100 OPP100
OPP100 OPP120
So at different OPPs of MPU it is safest to lock CORE at OPP_NOM.
Following are the DPLL locking frequencies at OPP NOM:
Core locks at 1000MHz
Per locks at 960MHz
LPDDR2 locks at 266MHz
DDR3 locks at 400MHz

Touching AM33xx files also to get DPLL values specific to board but no
functionality difference.

board/ppcag/bg0900/Makefile
drivers/bootcount/Makefile
include/configs/omap4_common.h
include/configs/pdnb3.h

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:

board/compulab/common/Makefile
board/udoo/Makefile

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.

include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.

Note: 'git show' will also list two files just because
they are new:

include/configs/am335x_igep0033.h
include/configs/omap3_igep00x0.h
