hwspinlock/omap: Add support for TI K3 SoCs
A HwSpinlock IP is also present on the newer TI K3 AM65x and J721E family of SoCs within the Main NavSS sub-module. Reuse the existing OMAP Hwspinlock driver to extend the support for this IP on K3 AM65x SoCs as well. The IP has slightly different bit-fields in the SYSCONFIG and SYSSTATUS registers.
