From: Hou Zhiqiang <zhiqiang....@nxp.com> Add an new IRQ chip declaration for LS1043A and LS1088A - compatible "fsl,ls1043a-extirq" for LS1043A, LS1046A. - compatible "fsl,ls1088a-extirq" for LS1088A, LS208xA, LX216xA. - get mask value directly according to compatible property of DT and remove confused code(bit_reverse field of struct ls_extirq_data, no need this field for SoC LS1021A. Because the register LS1021A_SCFGREVCR is initialized to 0xffffffff by the relative rcw)
