Subject: [PATCH 11/14] arm64: renesas: rzg3s-smarc-som: Invert the logic for SW_SD2_EN macro

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

The intention of SW_SD2_EN macro was to reflect the state of SW_CONFIG3
switch available on RZ/G3S Smarc Module. According to documentation SD2
is enabled when switch is in OFF state. For this, changed the logic of
marco to map value 0 to switch's OFF state and value 1 to switch's ON
state. Along with this update the description for each state for better
understanding.

The value of SW_SD2_EN macro was not changed in file because, according to
documentation, the default state for this switch is ON.

Fixes: adb4f0c5699c ("arm64: dts: renesas: Add initial support for RZ/G3S SMARC SoM")
