Get rid of k3-j721e-r5-*-u-boot.dtsi as it is not
necessary. Change the inclusion hierarchy to be as follows:
k3-j721e-<board>.dts---
-
-->k3-j721e-r5-<board>.dts
-
k3-j721e-<board>-u-boot.dtsi---
Reason for explicitly mentioning the inclusion of -u-boot.dtsi in code
although it could've been automatically done by U-Boot is to resolve
some of the dependencies that R5 file requires.
Also remove duplicate phandles while making this shift as well as remove
firmware-loader as it serves no purpose without "phandlepart" property.

Kernel commit d93036b47f35 ("arm64: dts: ti: k3-j721e-mcu_wakeup: Add
HyperBus node") was merged to kernel without its dependent patch [1].
Similar fix is needed in U-Boot, and hbmc currently breaks boot. Till
this gets fixed in U-Boot, disable the config by default so that the
hbmc probe that happens in board/ti/j721e/evm.c will not take place
and lead to boot failure.

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
(followed by J721E), get_timer() is called which eventually calls
dm_timer_init() to grab the tick-timer, which is mcu_timer0. Since we
need to set up the clocks before using the timer, move clk_k3 driver
probe before k3_sysfw_loader to ensure we have all necessary clocks set
up before.

- Dual CAN peripheral configuration:

bxCAN and the 512-byte SRAM memory.
* CAN2: Secondary bxCAN with no direct access to the SRAM memory.
This means that the two bxCAN cells share the 512-byte SRAM memory and
CAN2 can't be used without enabling CAN1.
- Single CAN peripheral configuration:
* CAN3: Primary bxCAN with dedicated Memory Access Controller unit and
512-byte SRAM memory.
