Subject: [PATCH v3 6/9] ARM: dts: Add arm,pl330-broken-no-flushp quirk for rk3288 platform

From: Addy Ke <addy.ke@...k-chips.com>

Pl330 integrated in rk3288 platform doesn't support
DMAFLUSHP function. So we add arm,pl330-broken-no-flushp quirk
for it. Also we add rockchip,i2s-broken-burst-len and
rockchip,spi-broken-burst-len to fix this problem.
