platform: arm64: drop the vacuous THERMAL dependency from EC_ASUS_GLYMUR

'depends on THERMAL || THERMAL=n' is always true and is semantically a
no-op, but it couples NEW_LEDS, which is selected here, to THERMAL and
closes a Kconfig dependency loop. The C tools stay silent because they
fold the always-true expression to 'y' before running dependency loop
detection; kconfiglib, used by the Yocto kernel config audit, does not
fold and rejects the config at parse time.

The loop is easy to expose with the in-tree tools, using the technique
from commit b33a654a5b ("drm/tiny: Kconfig: Remove always-y THERMAL
dep. from TINYDRM_REPAPER"),
https://git.kernel.org/linus/b33a654a5bd6: temporarily make THERMAL
tristate so the folding stops, then any config target reports it:

  $ sed -i 's/bool "Thermal drivers"/tristate "Thermal drivers"/' \
      drivers/thermal/Kconfig
  $ make allnoconfig
  error: recursive dependency detected!
	symbol POWER_SUPPLY is selected by HID_ASUS
	symbol HID_ASUS depends on LEDS_CLASS
	symbol LEDS_CLASS depends on NEW_LEDS
	symbol NEW_LEDS is selected by EC_ASUS_GLYMUR
	symbol EC_ASUS_GLYMUR depends on THERMAL
	symbol THERMAL is selected by AB8500_BM
	symbol AB8500_BM depends on POWER_SUPPLY

Drop the vacuous line to break the loop; the driver still builds both
with and without THERMAL.
