At present the MD5 option cannot be enabled by board configs since it has
no Kconfig name. It is generally enabled, so long as FIT support is
present. But not all boards use FIT, particularly in SPL
Fix this and add an option for SPL as well. This allows board code to call
md5() even if FIT support is not enabled.

To fill the exponent field of the rsa_public_key struct, rsa_mod_exp_sw
did a cast to uint64_t of the key_prop->public_exponent field.
But that alignment is not guaranteed in all cases.
This came to light when in my spl-fit-signature the key-name exceeded
a certain length and with it the verification then started failing.
(naming it "integrity" worked fine, "integrity-uboot" failed)
key_prop.public_exponent itself is actually a void-pointer, fdt_getprop()
also just returns such a void-pointer and inside the devicetree the 64bit
exponent is represented as 2 32bit numbers, so assuming a 64bit alignment
can lead to false reads.
So just use the already existing rsa_convert_big_endian() to do the actual
conversion from the dt's big-endian to the needed uint64 value.

The callback member of struct env_entry is always NULL for an SPL

SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded
in struct env_entry_node - i.e. about 2KB for the normal case of
512+change hash table entries.
Two small fixups are needed for this, all other references to the
callback member are already under !CONFIG_SPL_BUILD: Don't initialize
.callback in set_flags() - hsearch_r doesn't use that value
anyway. And make env_callback_init() initialize ->callback to NULL for
a new entry instead of relying on an unused or deleted entry having
