[PATCH 6.18.y 1/2] firmware: qcom_scm: Rename peripheral as pas_id

[Sasha Levin <sashal@kernel.org>]

From: Mukesh Ojha <mukesh.ojha@oss.qualcomm.com>

[ Upstream commit 69054348cc1c2d87acad90aec5e6e0d191012aff ]

Peripheral and pas_id refers to unique id for a subsystem and used only
when peripheral authentication service from secure world is utilized.

Lets rename peripheral to pas_id to reflect closer to its meaning.
