The spl_phase() function indicates whether U-Boot is in SPL and before
or after relocation. But sometimes it is useful to check for SPL with
zero code-size impact. Since spl_phase() checks the global_data flags,
it does add a few bytes.
Add a new spl_in_proper() function to check if U-Boot proper is
running, regardless of the relocation status.

Typically the bloblist is set up after the devicetree is present. This
makes sense because bloblist may use malloc() to allocate the space it
needs.
However sometimes the devicetree itself may be present in the bloblist.
In that case it is at a known location in memory so we can init the
bloblist very early, before devicetree.
Add a flag to indicate whether the bloblist has been inited. Add a
function to init it only if needed. Use that in the init sequence.

For U-Boot proper we have CONFIG_SYS_MALLOC_F which indicates that a
malloc() pool is available before relocation.
For SPL we only have CONFIG_SPL_SYS_MALLOC_F_LEN which indicates the
size of the pool.
In various places we use CONFIG_SPL_SYS_MALLOC_F_LEN == 0 to indicate
that there is no pool.
This differing approach is confusing. Add a new CONFIG_SPL_SYS_MALLOC_F
symbol for SPL (and similarly for TPL and VPL). Tidy up the Kconfig
help for clarity.
For now these symbols are not used. That is cleaned up in the following

Reason for explicitly mentioning the inclusion of -u-boot.dtsi in code

When setting up boot media to load the TIFS binary in legacy boot flow
(followed by J721E), get_timer() is called which calls dm_timer_init()
which then gets the tick-timer: mcu_timer0. mcu_timer0 uses k3_clks
(clock controller) and k3_pds (power controller) from the dmsc node that
forces probe of the ti_sci driver of TIFS that hasn't been loaded yet!
Running ti_sci_cmd_get_revision from the probe leads to panic since no
TIFS and board config binaries have been loaded yet. Resolve this by
moving ti_sci_cmd_get_revision to ti_sci_get_handle_from_sysfw as a
common point of invocation for both legacy and combined boot flows.
Before doing this, it is important to go through whether any sync points
exist where revision is needed before ti_sci_get_handle_from_sysfw is
invoked. Going through the code along with boot tests on both flows
ensures that there are none.

When setting boot media to load the TIFS binary in legacy boot flow
