In some cases, a single SerDes instance can be shared between two different
processors, each using a separate link. In these cases, the SerDes
configuration is done in an earlier boot stage. Therefore, add support to
skip reconfiguring, if it is was already configured beforehand.

The PLL_CMNLC clocks are modelled as a child clock device of seirra. In the
function device_probe, the corresponding clocks are probed before calling
the device's probe. The PLL_CMNLC mux clock can only be created after the
device's probe. Therefore, move assigned-clocks and assigned-clock-parents
to the link nodes in U-Boot device tree file.

Sierra has two PLLs, PLL_CMNLC and PLL_CMNLC1 and each of these PLLs has
two inputs, plllc_refclk (input from pll0_refclk) and refrcv (input from
pll1_refclk). Model PLL_CMNLC and PLL_CMNLC1 as a clock so that it's
possible to select one of these two inputs from device tree.

Cadence Sierra PHY driver registers PHY using devm_phy_create()
for all sub-nodes of Sierra device tree node. However Sierra device
tree node can have sub-nodes for the various clocks in addtion to the
PHY. Use devm_phy_create() only for nodes with name "phy" (or "link"
for old device tree) which represent the actual PHY.

Commit 39b823381d9d ("phy: cadence: Add driver for Sierra PHY")
de-asserts PHY_RESET even before the configurations are loaded in
phy_init(). However PHY_RESET should be de-asserted only after
all the configurations has been initialized, instead of de-asserting
in probe. Fix it here.

First check the presence of the ipu firmware in the boot partition.
If present enable the ipu and the related clocks & then move
on to load the firmware and eventually start remoteproc IPU1/IPU2.
do_enable_clocks by default puts the clock domains into auto
which does not work well with reset. Hence adding do_enable_ipu_clocks
function.

The J721S2 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration in automotive ADAS applications and
industrial applications requiring AI at the network edge. This SoC extends
the Jacinto 7 family of SoCs with focus on lowering system costs and power
while providing interfaces, memory architecture and compute performance for
single and multi-sensor applications.
Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, three clusters of lockstep capable
dual Cortex-R5F MCUs, Deep-learning Matrix Multiply Accelerator(MMA), C7x
floating point Vector DSP.
* 3D GPU: Automotive grade IMG BXS-4-64
* Vision Processing Accelerator (VPAC) with image signal processor and
Depth and Motion Processing Accelerator (DMPAC)
* Two CSI2.0 4L RX plus one eDP/DP, two DSI Tx, and one DPI interface.
* Two Ethernet ports with RGMII support.
* Single 4 lane PCIe-GEN3 controllers, USB3.0 Dual-role device subsystems,
* Up to 20 MCANs, 5 McASP, eMMC and SD, OSPI/HyperBus memory controller,
QSPI, I3C and I2C, eCAP/eQEP, eHRPWM, MLB among other peripherals.
* Hardware accelerator blocks containing AES/DES/SHA/MD5 called SA2UL
management.

However, we do not need parentheses enclosing the values for this
