The dtb should be embedded in the u-boot-spl image so that
the CONFIG_SPL_TARGET of spl/u-boot-spl.hex includes it.

This also affects the main u-boot image, so adjust
CONFIG_SPL_FS_LOAD_PAYLOAD_NAME to u-boot.img which now
also includes the dtb.

Stratix10 combines the u-boot-spl image into the fpga configuration
bitstream so that the SDM can load the processors memory.  This
process requires a hex format of the u-boot-spl image.
CONFIG_SPL_TARGET is set to "spl/u-boot-spl.hex"

Some devices, namely Intel's stratix10 SoC, require u-boot-spl in

Add code to reset all reset signals as in gpio DT node. A reset property
is an optional feature, so only print out a warning and do not fail if a
reset property is not present.

If a reset property is discovered, then use it to deassert, thus
bringing the IP out of reset.

DM_I2C_COMPAT is somehow being enabled outside of Kconfig, so
this explicitly undefines it in the header file, and brackets

Enabling DM_PMIC, DM_REGULATOR_FIXED, and DM_REGULATOR_GPIO

With CONFIG_BLK becoming a requirement, the Davinci MMC driver

The GPIO banks are broken up into two 16-bit registers for each
bank set.  Unfortunately, the math that determines how to shift
blindly shifted by the number of the gpio.  This worked for gpio
numbers under 32, but higher gpio's are broken.  This fixes the
gpio index, so the bank is passed and the shift amount within
the register is passed now instead of the gpio number.
