arm64: dts: ls1028a: Fix CPU idle fail.

[ Upstream commit 53f2ac9d3aa881ed419054076042898b77c27ee4 ]

PSCI spec define 1st parameter's bit 16 of function CPU_SUSPEND to
indicate CPU State Type: 0 for standby, 1 for power down. In this
case, we want to select standby for CPU idle feature. But current
setting wrongly select power down and cause CPU SUSPEND fail every
time. Need this fix.
