TI Driver updates for v5.18

* Fixups for k3-ringacc, smartreflex, tisci, wkup_m3_ipc
* Device detection for am62x.

* tag 'ti-driver-soc-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ti/linux:
  soc: ti: k3-socinfo: Add AM62x JTAG ID
  soc: ti: wkup_m3_ipc: Fix IRQ check in wkup_m3_ipc_probe
  firmware: ti_sci: inproper error handling of ti_sci_probe
  firmware: ti_sci: Fix compilation failure when CONFIG_TI_SCI_PROTOCOL is not defined
  soc: ti: smartreflex: Use platform_get_irq_optional() to get the interrupt
  soc: ti: k3-ringacc: Use devm_bitmap_zalloc() when applicable
