Subject: [PATCH] ARM: dts: am33xx: avoid invalid OCP device-link for timers

This patch fixes boot-time fw_devlink errors on AM335x/UCC3 caused
by invalid device-link creation attempts involving timer1/timer2
and supplier ocp.

Observed kernel log messages:

  ti-sysc 44e31000.target-module: Failed to create device link (0x180)
  with supplier ocp for
  /ocp/interconnect@44c00000/segment@200000/target-module@31000/timer@0

  ti-sysc 48040000.target-module: Failed to create device link (0x180)
  with supplier ocp for
  /ocp/interconnect@48000000/segment@0/target-module@40000/timer@0

The change updates dependency handling for timer1 and timer2 so the
kernel no longer attempts this invalid link-creation path during
initialization of supplier ocp.

Impact:

- Removes the two ti-sysc/fw_devlink error messages at boot
- Preserves current timer and clock assignment behavior
- No functional regression observed in boot and timer operation tests
