Hi All,
In u-boot, hbmc is broken and has been removed from j7200
configs. This series re-enables the hbmc driver and introduces a series
of hyperflash boot fixes. At present, in u-boot, the parent device (fss)
gets registered as a syscon device. This is done because the MMIO
mux driver in u-boot did not support the mux functionality when the
parent device is not a syscon. In this series, we make relevant changes
in the hbmc driver as well as dts' so that we can use the reg-mux driver for
selecting the appropriate state of the mux.

Updated PLL driver sequencing requires us to use udelay in the PLL
driver as there is no poll bit to get the status of operations.
tick-timer(mcu_timer0/main_timer0) setting up the clocks for itself is
something that won't work as the PLL driver will be using udelay and
PLLs are configured during clock probe which would end up in a recursive
probe.
tick-timer being used by K3 devices are configured by ROM and we really
don't need to configure any of the clocks.
Remove the clock dependency from R5 stage as we don't need to setup
clocks for it.

The j7200 SOC has a single DDR controller and hence no need for
configuring the MSMC interleaver. Hence we do not have an explicit node
for MSMC in j7200 DT, unlike j721s2/j784s4.
Also, MSMC clk id is described under A72SS0_CORE0 Device in TISCI
documentation [0].
Considering the above, define the MSMC clk in the a72 node.

Upstream DTS added explicit ranges to the fss node. It did not include the
32 bit memory space needed by the R5 to access OSPI. With the upstream DTS
sync, OSPI boot no longer works.
Adding the missing range here. It is also being added in the upstream DTS,
so after the next upstream DTS sync, this patch can be removed. See

Previously, dynamic frequency scaling supported rates only through fixed

This virtual clock mux configuration enables more varied rates on A72

Sync j7200 dts with Linux 6.6-rc1
- k3-j7200-r5-common-proc-board.dts now inherits from
k3-j7200-common-proc-board.dts instead of k3-j7200-som-p0.dtsi. This
allows us to trim down the r5 file considerably by using existing
properties
- remove pimux nodes from r5 file
- remove duplicate nodes & node properties from r5/u-boot files
- mcu_timer0 now used instead of timer1
mcu_timer0 device id added to dev-data.c file in order to work
- remove cpsw node
This node is no longer required since the compatible is now fixed
- remove dummy_clock_19_2_mhz
This node wasn't being used anyhere, so it was removed
- remove dummy_clock_200mhz
main_sdhci0 & main_sdhci1 no longer need dummy clock for eMMC/SD
- fix secure proxy node
mcu_secproxy changed to used secure_prxy_mcu which is already
defined in k3-j7200-mcu-wakeup.dtsi
- removed &mcu_ringacc property override since they're present in
v6.6-rc1
