MIPS: SEAD3: Use register-bit-led driver via DT for LEDs

Probe a driver for the PLED & FLED LEDs found on the SEAD3 board using
the register-bit-led driver via device tree, rather than a custom driver
via platform code. Enable support for the register-bit-led driver & its
prerequisite syscon in sead3_defconfig.
