[PATCH] arm64: dts: meson: fix PHY deassert timing requirements

The sync of the device tree and dt-bindings from Linux v5.6-rc2
11a48a5a18c6 ("Linux 5.6-rc2") causes Ethernet to break on some
ODROID-C2.
Meanwhile a fix to increase the reset timing has been added to Linux.
Instead of reverting the offending commit, use the new reset timing
from upstream Linux commit c183c406c432 ("arm64: dts: meson: fix PHY
deassert timing requirements").
Fixes: dd5f2351e99a ("arm64: dts: meson: sync dt and bindings from v5.6-rc2")
