Update the existing OMAP HwSpinlock binding to include the info for
AM64x SoCs. There are some minor IP integration differences between
the AM64x SoCs and the previous AM65x and J721E SoC families.

Update the AM65x HwSpinlock example to fix couple of warnings
that started showing up after the conversion of K3 bindings to
YAML format in commit 66e06509aa ("dt-bindings: arm: ti:
Convert K3 board/soc bindings to DT schema").
compatible: ['ti,am654'] is not valid under any of the given schemas (Possible causes of the failure):
compatible: ['ti,am654'] is too short
compatible:0: 'ti,am654' is not one of ['ti,am654-evm']
Also, fix one of the node names while at this.

Convert the current OMAP hwspinlock binding from text format to YAML
format/DT schema, and delete the legacy text binding file.
The new YAML binding conversion is a slightly updated version compared
to the original. The legacy "ti,hwmods" property is now obsolete and
is dropped altogether, and the K3 example is updated to showcase the
actual dts node usage.

In modern Qualcomm platforms the mutex region of the TCSR is forked off
into its own block, all with a offset of 0 and stride of 4096, and in
some of these platforms no other registers in this region is accessed
from Linux.
Update the binding to allow the hardware block to be described directly
on the mmio bus, in addition to allowing the existing syscon based
definition for backwards compatibility.

The TI K3 AM65x and J721E family of SoCs have a HwSpinlock IP that
is similar to the existing HwSpinlock IP present in OMAP architecture
based SoCs with minor differences. Update the existing OMAP HwSpinlock
binding for this IP on TI K3 AM65x and J721E SoCs. The same compatible
from AM65x SoCs is reused for J721E SoCs.

The Hardware Spinlock device on atlas7 provides hardware assistance
for synchronization between the multiple processors in the system
(dual Cortex-A7, CAN bus Cortex-M3 and audio DSP).
This patch adds the DT bindings information for this hwspinlock
module.

HwSpinlock IP is present only on OMAP4 and other newer SoCs,
which are all device-tree boot only. This patch adds the
DT bindings information for OMAP hwspinlock module.

This patch adds the generic common bindings used to represent
a hwlock device and use/request locks in a device-tree build.
Each hwspinlock provider should have the '#hwlock-cells' property,
which represents the number of cells to be used for representing
a specific hwspinlock. Client users shall use the property
'hwlocks' for requesting specific lock(s).
Note that the document is named hwlock.txt deliberately to keep
it a bit more generic.
