Subject: [PATCH RESEND] arm64: dts: mediatek: mt7622: readd syscon to pciesys
 node

From: Christian Marangi <ansuelsmth@...il.com>

The sata node references the pciesys with the property
mediatek,phy-mode and that is used as a syscon to access the pciesys
registers.

Readd the syscon compatible to pciesys node to restore correct
functionality of the SATA interface.
