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.

The OMAP hwspinlock users will use a 0-indexed relative hwlock number as
|
|
the argument specifier value for requesting a specific hwspinlock within
|
|
a hwspinlock bank.
|
|
|
