    arm64: dts: actions: limit address range for pinctrl node
    
    [ Upstream commit 4bb1eb3cd4bd6241d5e5f99bbfd801ea5a007b6c ]
    
    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.
    
    One way to fix it, is to limit pinctrl address range which is safe
    to do as current pinctrl driver uses address range only up to 0x100.
    
    This commit limits the pinctrl address range to 0x100 so that it doesn't
    conflict with sps range.

    Semi S700")
