[spp] [PATCH 4/6] shared/sec: rename func for parsing port UID

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

This update is to rename `decode_port_value()` to `parse_port_uid()`
because it is not for decoding but parsing resource UID of port such
as `phy:0`, and the term `port value` is ambiguous.

Signed-off-by: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>
