MAINTAINERS: add entry for Maxim PMICs on Samsung boards

Add myself and Chanwoo Choi as supporters to help in reviewing patches
for Maxim 77686 PMIC and Maxim 14577/77693 MUIC drivers:
 - mfd (all of them),
 - extcon (extcon-max14577.c, extcon-max77693.c),
 - regulator (all of them),
 - clock (clk-max77686.c),
 - RTC (rtc-max77686.c).

Lately I am the author of contributors to them. These drivers are used
on Exynos-based boards (Trats 2, Gear 1 and Gear 2).
