[PATCH 2/4] csky: apply page shift to PFN instead of VA in pfn_to_virt

From: Yan Zhao
Date: Wed Jan 31 2024 - 01:28:51 EST


Apply the page shift to PFN to get physical address for final VA.
The macro __va should take physical address instead of PFN as input.

Fixes: c1884e1e1164 ("csky: Make pfn accessors static inlines")
