[PATCH] soc: aspeed: uart-routing: Use __sysfs_match_string

[Joel Stanley]

From: Zev Weiss <zev@bewilderbeest.net>

The existing use of match_string() caused it to reject 'echo foo' due
to the implicitly appended newline, which was somewhat ergonomically
awkward and inconsistent with typical sysfs behavior.  Using the
__sysfs_* variant instead provides more convenient and consistent
linefeed-agnostic behavior.
