Subject: [PATCH v2 04/10] arm64: dts: actions: *do not merge* disable sps node from S700

After commit 7cdf8446ed1d ("arm64: dts: actions: Add pinctrl node for
Actions Semi S700") following error has been observed while booting
Linux on Cubieboard7-lite(based on S700 SoC).

[    0.257415] pinctrl-s700 e01b0000.pinctrl: can't request region for
resource [mem 0xe01b0000-0xe01b0fff]
[    0.266902] pinctrl-s700: probe of e01b0000.pinctrl failed with error -16

This is due to the fact that memory range for "sps" power domain controller
clashes with pinctrl.

This commit disable "sps" to avoid this conflict and let us test DMA and MMC
related changes.
