If we want to properly unload images in Exit() the memory should always be
allocated in the same way. As we allocate memory when reading from file we
should do the same when the original image is in memory.

A further patch will be needed to free the memory when Exit() is called.

This patch adds distro boot commands for qspi, ospi and mmc.
The distro boot commands now reads the script from flash offset
of 63.5MB  for qspi and ospi and executes it. For mmc its same
as generic distro boot command. As either one of the qspi or ospi can
exist on hardware, defined a single distroboot command as xspi
that works for both.

Setup default location via script_offset_f to 63.5MB to match the most
xilinx reference boards for qspi, ospi for now.

The aim of this patch is not to have temporary variables used in
distro_bootcmd left as environment variables after run something.
See the discussion[1].
Without this patch, saveenv command also saves those variables, too.
While they are apparently safe, scsi_need_init can be harmful.

Please note that, in most cases, a variable should be converted to
hush's local variable, while "devplist" cannot because it is created
by "part" command as an environment variable.

has changed the alignment of efi_guid_t. This changed the size of
struct efi_configuration_table on 32-bit systems form 20 to 24 bytes. As
an array of this type is pointed to by the system table this breaks
compatibility with existing versions of GRUB and Linux. Let's get back the
original size by using the attribute __packed.

regulator_set_enable() api throws an error in the following three cases:
- when requested to disable an always-on regulator
- when set_enable() ops not provided by regulator driver
- when enabling is actually failed.(Error returned by the regulator driver)

Sometimes consumer drivers doesn't want to track the first two scenarios
and just need to worry about the case where enabling is actually failed.
But it is also a good practice to have an error value returned in the
first two cases.

So introduce an api regulator_set_enable_if_allowed() which ignores the
first two error cases and returns an error as given by regulator driver.
Consumer drivers can use this api need not worry about the first two
error conditions.

The board_r init function was complaining that we are looping through
an array, calling all our tiny init stubs sequentially via indirect
function calls (which can't be speculated, so they are slow).

The solution to that is pretty easy though. All we need to do is inline
the function that loops through the functions and the compiler will
automatically convert almost all indirect calls into direct inlined code.

With this patch, the overall code size drops (by 40 bytes on riscv64)
and boot time should become measurably faster for every target.
