[PATCH AUTOSEL for 3.18 050/101] ACPI: EC: Fix EC command visibility for dynamic debug

[Sasha Levin]

From: Lv Zheng <lv.zheng@xxxxxxxxx>

[ Upstream commit 4625d752e600c116e6327f9d7fc16e8f5be107e9 ]

acpi_ec_cmd_string() currently is only enabled for "DEBUG" macro, but users
trend to use CONFIG_DYNAMIC_DEBUG and enable ec.c pr_debug() print-outs by
"dyndbg='file ec.c +p'". In this use case, all command names are turned
into UNDEF and the log is confusing. This affects bugzilla triage work.

This patch fixes this issue by enabling acpi_ec_cmd_string() for
CONFIG_DYNAMIC_DEBUG.
