[PATCH 1/3] sunxi: spl: fix SPL_SUNXI_LED active low configuration

[Andre Przywara]

The newly introduced Allwinner SPL LED "framework" defined a
SPL_SUNXI_LED_STATUS_STATE Kconfig symbol, that was supposed to denote
the active-low vs. active-high polarity of the LED. However this is
a bool symbol, so it will simply vanish if not defined, and we cannot use
it directly inside a C statement.

Filter the symbol through the IS_ENABLED() macro, which will return 0 if
the symbol is not defined, which is the intended value here.

This fixes configuring LEDs with active-low polarity.
