struct sunxi_prcm_reg is naturally packed. There is no need to define it as packed. Defining it as packed leads to compilation errors with GCC 9.2.1:

CC arch/arm/lib/reloc_arm_efi.o arch/arm/cpu/armv7/sunxi/psci.c: In function ‘sunxi_cpu_set_power’: :qarch/arm/cpu/armv7/sunxi/psci.c:163:21: error: taking address of packed member of ‘struct sunxi_prcm_reg’ may result in an unaligned pointer value [-Werror=address-of-packed-member] 163 | sunxi_power_switch(&prcm->cpu_pwr_clamp[cpu], &prcm->cpu_pwroff, | ^~~~~~~~~~~~~~~~~~~~~~~~~

Remove __packed attribute from struct sunxi_prcm_reg.
