[PATCH] arm64: configs: defconfig: Convert TISCI to modules

[Nishanth Menon]

Now that all relevant drivers have are ready, convert the
TISCI drivers to modules. This impacts all K3 platforms for
boot, recommendation (based on empirical evidence) is to use
deferred_probe_timeout=60 in kernel command line to allow for driver
probes to complete successfully based on the initrd used.

NOTE:
a) This patch is based off v7.3-rc1 and will create a merge conflict
  in linux-next (next-20260909), but the resolution is trivial (vs
  bd94bea7165be450903c6d64bbcb4862e36798f9).
b) Emperical experiments that Siddharth Vadapalli did,
  it seems like some driver probes might be taking much
  longer than the default deferred_probe_timeout of 10
  seconds that is used when CONFIG_MODULES=y. Testing log[1]
  a deferred_probe_timeout=60 seems to have worked fine.
c) Full bloatometer report is available in [1] as well.
d) related lore discussions[2]
