phy: core: Remove unused phy_pm_runtime_(allow|forbid)

Commit Message

Dr. David Alan Gilbert March 6, 2025, 1:54 a.m. UTC

From: "Dr. David Alan Gilbert" <[e-mail]>

phy_pm_runtime_allow() and phy_pm_runtime_forbid() were added in 2013
as part of
commit ff764963479a ("drivers: phy: add generic PHY framework")
but have remained unused.

Remove them.
Fix up the (English) docs - I've left the Chinese translation.
