k210: dts: align fpioa node with Linux

Browse source 
Linux kernel fpioa pinctrl driver expects the sysctl phandle and the
power bit offset of the fpioa device to be specified as a single
property "canaan,k210-sysctl-power".
Replace the "canaan,k210-sysctl" and "canaan,k210-power-offset"
properties with "canaan,k210-sysctl-power" to satisfy the Linux kernel
requirements. This new property is parsed using the existing function
dev_read_phandle_with_args().
