arm64/am62x: Add TISCI client, GPIO and I2C drivers
On K3 SoCs the A53 cluster does not own device power, clocks, resets or
interrupt routing; these are managed by the DM/TIFS firmware and requested
over TISCI through the secure-proxy mailbox.  Add:

  - a TISCI client (secure-proxy transport plus device/clock/reset helpers)
  - a GPIO driver for banks 0/1 with pad mux and TISCI power-on
  - an OMAP-I2C driver for the main-domain I2C controllers

and wire them into the PocketBeagle2 and BeaglePlay bring-up.

Tested on PocketBeagle2 (SYSFW 11.2.5) with the TechLab cape attached:

  nsh> i2c bus
  nsh> i2c dev -b 0 0x03 0x77   # I2C0 detects onboard 0x20 and 0x50
  nsh> gpio -o 1 /dev/gpio3     # drives a user LED; read back with:
  nsh> gpio /dev/gpio3
