The update_efs_spi_speed allows changing the SPI speed manually in a
binary that has already been built. This will allow binaries not built
for the EM100 SPI ROM emulator to be updated so that they will work.
There is a corresponding change that will check to see if the EFS value
has been modified from the original speed and will prevent coreboot from

Even though `device` entries are children of `chip` entries in the
devicetree source format, the chips in the translated C structures
are only hooked up to device nodes. Hence, any chip with all its
settings will be silently dropped by sconfig if there is no device
node below it.
Let's adapt the parser to ensure that there is at least one `device`
entry. The intermediate `chipchildren_dev` rule applies until the
first `device` entry is found, then everything continues as before
with the `chipchildren` rule.

No need to do raw GPIO MMIO accesses when basically the same
functionality can be achieved by using existing APIs. Using the existing
GPIO API instead of raw GPIO MMIO register accesses allows containing
all direct GPIO MMIO accesses inside the common AMD GPIO code which will
be done in subsequent patches. Since the value parameter of gpio_set is
int, change the type of the val parameter of drive_scl to int as well
even though I'm not sure why a signed integer was used for this in the
common GPIO API. Since program_gpios already configures the SCL GPIOs as
outputs, gpio_set can be used in drive_scl which only sets the output
value, but doesn't configure the direction.
TEST=The waveform on the SCL pin of I2C3 on a barla/careena Chromebook
looks similar to the same as before during the reset_i2c_peripherals
call, but due to the additional overhead of the read-modify-write to the
GPIO register instead of just a write, the pulse width gets about 50%
longer. Since the udelay call in drive_scl still has an open TODO to
make this configurable and the pulses being longer is in the safe side,
this side-effect can be addressed in a follow-up patch.

drive_scl in soc/amd/common/block/i2c/i2c.c writes the raw GPIO MMIO
configuration register and drives it as output, so don't initially
configure the GPIO as input with no pull up/down. This is a preparation
to use the common AMD GPIO access functions instead of the raw register
accesses, since the gpio_set function only sets the output value, but
doesn't reconfigure the direction. Using gpio_output there instead would
reconfigure the direction as well, but would result in doubling the
number of MMIO accesses, so just configure the GPIOs correctly right
away to avoid that.
