Using PLATFORM=k3 can leads to a runtime boot crash on some K3 SoC (e.g.
j721e) because the optee flavor is missing.

We could use BR2_TARGET_OPTEE_OS_PLATFORM=k3 and
BR2_TARGET_OPTEE_OS_PLATFORM_FLAVOR=am64x but we actually can use
BR2_TARGET_OPTEE_OS_PLATFORM=k3-am64x as explained in the optee-os
Makefile [1]:

  # If $(PLATFORM) is defined and contains a hyphen, parse it as
  # $(PLATFORM)-$(PLATFORM_FLAVOR) for convenience

This is how meta-ti set the optee-os platform:

  meta-ti]$ git grep OPTEEMACHINE
  meta-ti-bsp/conf/machine/am437x-hs-evm.conf:OPTEEMACHINE = "ti-am43xx"
  meta-ti-bsp/conf/machine/am57xx-hs-evm.conf:OPTEEMACHINE = "ti-am57xx"
  meta-ti-bsp/conf/machine/beagleplay.conf:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/dra7xx-hs-evm.conf:OPTEEMACHINE = "ti-dra7xx"
  meta-ti-bsp/conf/machine/include/am62axx.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/am62pxx.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/am62xx.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/am64xx.inc:OPTEEMACHINE = "k3-am64x"
  meta-ti-bsp/conf/machine/include/am65xx.inc:OPTEEMACHINE = "k3-am65x"
  meta-ti-bsp/conf/machine/include/j7200.inc:OPTEEMACHINE = "k3-j721e"
  meta-ti-bsp/conf/machine/include/j721e.inc:OPTEEMACHINE = "k3-j721e"
  meta-ti-bsp/conf/machine/include/j721s2.inc:OPTEEMACHINE = "k3-j784s4"
  meta-ti-bsp/conf/machine/include/j722s.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/j784s4.inc:OPTEEMACHINE = "k3-j784s4"

  meta-ti uses the OPTEEMACHINE to set optee-os platform [2].
