arm64: defconfig: Remove CONFIG_SPS from lahaina_debug.config

lahaina_QGKI.config takes care of enabling CONFIG_SPS and CONFIG_USB_BAM
in lahaina_debug.config. CONFIG_USB_BAM depends on CONFIG_SPS. Currently
CONFIG_SPS is enabled in both lahaina_debug.config and lahaina_QGKI.config
whereas CONFIG_USB_BAM is enabled only in lahaina_QGKI.config and also
explicitly marked as "not set" in lahaina_debug.config. This conflict
between the fragments results into CONFIG_USB_BAM remaining disabled in
the combined lahaina-qgki-debug_defconfig. Clean this up by removing
their redundant entries from lahaina_debug.config so that both CONFIG_SPS
and CONFIG_USB_BAM are only enabled in the lahaina_QKI.config fragment.
