edp: tn8: configure sysedp for P1761-A02

This patch adds sysedp_batmon configuration via device tree to
P1761-A02 hardware. The battery data is from preliminary
characterization and currently only for room temperature. The
parameters are following:
 * Battery impedance 70mOhm through entire state-of-charge
 * Board resistance 40mOhm
 * Battery OCV look-up table (4.25V@100% -> 3.4V@0%)
 * VSYSMIN 3.0V
 * Battery max current (9A @ 25C-50C)
