According to the latest datasheet(Rev. C Draft 1, 10/2015) of
i.MX7D, change the VDD_SOC voltage to 0.95V in run mode, and
add a 25mV margin to cover the IR drop and board tolerance.
So setting VDD_SOC voltage to 0.975V.

This mx7d 19x19 lpddr2 arm2 board is based on 19x19 lpddr3 arm2 board
with DDR changed to 512M LPDDR2. We added DDR script for LPDDR2 and
a new u-boot build target: mx7d_19x19_lpddr2_arm2_config
LPDDR2 script source: lpddr2_0_1.ds

Datasheet Rev-B defines standby voltage as 1V for i.MX7D, we add
25mV for board level IR drop.

To CD/VSELECT/RST, should use same pad settings with USDHC_PAD_CTRL,
because default NO_PAD_CTRL's settings is 100K Pull-Down. But, we need
pull-up for CD/VSELECT/RST.
Also some board provides external pull-down/up, we'd better use internal
pull-up for these pad settings.
To mx7d_12x12_lpddr3_arm2:
If no card plugged in, "mmc dev 1" will show "Card did not respond to
voltage select". After apply this patch, it will show "MMC: no card present".
To mx7dsabresd:
Alougth without this patch, if no card plugged in sd1, still correct msg
"MMC: no card present", anyway we'd better use pull-up.

Since the flash blocks are locked at default , need to set
"CONFIG_SYS_FLASH_PROTECTION" to unlock them before write/erase.
The patch also add the pinmux for LBA (ADV) pin and set eimnor enabled at
default.

On MX7D, boot rom can provide some boot information such as boot device,
arm freq, axi freq, etc. (see the structure below)
Offset Byte4 | Byte3 | Byte2 | Byte1
0x0 Reserved | Boot Device Type | Boot Device Instance | Reserved
0x4 ARM core frequency(in Hz)
0x8 AXI bus frequency(in Hz)
0x0C DDR frequency(in Hz)
0x10 GPT1 input clock frequency(in Hz)
0x14 Reserved
0x18
0x1C
The boot information can be accessed by get the pointer at 0x1E8. This patch
changes the u-boot to use the new approach. When manufacture boot, the info
recorded is the actual SD port, not the failed device.
