Add a missing initialization of gd->env_valid in env_ext4_load
as it is already done in some other env device.

Set gd->env_valid = ENV_VALID in env_ext4_save() and env_ext4_load().

This patch allows to have a correct information in 'env info' command.

This patch adds prototypes for several weak functions:
- env_ext4_get_intf
- env_ext4_get_dev_part
- env_get_location

It solves the following warnings when compiling with W=1

As part of the EFI self test we set and check the serial# variable.
However, we should not be forcing this setting.  In the case where we
are allowed to change the variable it will change, and we will pass the
test.  In the case where we cannot change it, force may or may not be
allowed, depending on further environment restrictions.  Drop the -f
flag here as we do not need it.

Add API to save boot parameters passed from BL31

Use assembly implementation of save_boot_params instead of c function.
Because generally ATF does not set up SP_EL2 on exiting.
Thus, usage of a C function immediately after exiting with no stack
setup done by ATF explicitly, may cause SP_EL2 to be not sane,
which in turn causes a crash if this boot was not lucky to get
an SP_EL2 in valid range. Replace C implementation with assembly one
which does not use stack this early, and let u-boot to set up its stack
later.
