ARM: dts: rockchip: add sram to bus_intmem nodename for rk3036

A test with the command below gives these errors:

arch/arm/boot/dts/rk3036-evb.dt.yaml:
bus_intmem@10080000: $nodename:0: 'bus_intmem@10080000'
does not match '^sram(@.*)?'
arch/arm/boot/dts/rk3036-kylin.dt.yaml:
bus_intmem@10080000: $nodename:0: 'bus_intmem@10080000'
does not match '^sram(@.*)?'

Fix this error by adding sram to the bus_intmem nodename
in rk3036.dtsi.
