This patch enables DM_SERIAL for the pandora board. Verified that
the default kernel can still be booted with this.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Now CONFIG_GENERIC_MMC and CONFIG_MMC match for all defconfig.
We do not need two options for the same feature. Deprecate the
former.
This commit was generated with the sed script 's/GENERIC_MMC/MMC/'
and manual fixup of drivers/mmc/Kconfig.

This introduces omap_die_id_display to display the full die id.
There is no need to store it in an environment variable, that no boot script
is using anyway.

Boards using the TWL4030 regulator may not all use the LDOs the same way
(e.g. MMC2 power can be controlled by another LDO than VMMC2).
This delegates TWL4030 MMC power initializations to board-specific functions,
that may still call twl4030_power_mmc_init for the default behavior.

u-boot standard i2c register write prototype is
i2c_reg_write(u8 addr, u8 reg, u8 val)
twl4030_i2c_write_u8(u8 addr, u8 val, u8 reg)
does not provide consistency, so switch the prototype to be
consistent with rest of u-boot i2c operations:
twl4030_i2c_write_u8(u8 addr, u8 reg, u8 val)

Update pandora's GPIO setup code with these changes:
- convert to gpiolib
- set up dual voltage GPIOs to match supply of 1.8V by clearing VMODE1
- add GPIO_IO_PWRDNZ configuration for DM3730 variation of pandora
(required to enable GPIO 126, 127, and 129 I/O cells in DM3730)
- add wifi reset pulse as recommended by wifi chip's manufacturer
- drop configuration of GPIOs that u-boot doesn't need

Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency. While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.

These regulators are not needed to start the kernel and only
cause "incomplete constraints" warnings from kernel, so don't
turn them on to save power.

Not all boards have both LEDs hooked, so enabling both on
boards with single LED will just waste power. Make it
possible to choose LEDs by adding argument to
twl4030_led_init().
Using this turn on only LEDB for pandora, leave both LEDs
on for all other boards, as it was before this patch.
