arm64: dts: uniphier: fix input delay value for legacy mode of eMMC

[ Upstream commit f4e5200fc0d7dad75c688e7ccc0652481a916df5 ]

The property of the legacy mode for the eMMC PHY turned out to
be wrong.  Some eMMC devices are unstable due to the set-up/hold
timing violation.  Correct the delay value.
