This patch series adds support for SM5504 to the existing extcon-sm5502
driver. SM5502 and SM5504 are fairly similar so support for SM5504 can
be added with a few simple changes to the code.

I tested this patch series on both SM5502 (Samsung Galaxy A5 2015)
and SM5504 (Samsung Galaxy S4 Mini Value Edition) and it seems to work
just fine for both.

Changes in v4:
  - Add NULL check for .parse_irq (suggested by Chanwoo Choi)
  - Add Rob's Acked-by: on the dt-bindings patch
Changes in v3:
  - Drop patch 1-4 (already applied)
  - Avoid if (type == TYPE_SM5504) everywhere in the code, instead
    introduce a struct sm5502_type that encodes chip-specific information.
Changes in v2: Fix compile warning in last patch
