sunxi: psci: avoid error address-of-packed-member
Compiling with GCC 9.2.1 leads to build errors: arch/arm/cpu/armv7/sunxi/psci.c: In function ‘sunxi_cpu_set_power’: arch/arm/cpu/armv7/sunxi/psci.c:144:21: error: taking address of packed member of ‘struct sunxi_cpucfg_reg’ may result in an unaligned pointer value [-Werror=address-of-packed-member] 144 | sunxi_power_switch(&cpucfg->cpu1_pwr_clamp, &cpucfg->cpu1_pwroff, | ^~~~~~~~~~~~~~~~~~~~~~~ arch/arm/cpu/armv7/sunxi/psci.c:144:46: error: taking address of packed member of ‘struct sunxi_cpucfg_reg’ may result in an unaligned pointer value [-Werror=address-of-packed-member] 144 | sunxi_power_switch(&cpucfg->cpu1_pwr_clamp, &cpucfg->cpu1_pwroff, | ^~~~~~~~~~~~~~~~~~~~ Use memcpy() and void* pointers to resolve the problem caused by packing the struct sunxi_cpucfg_reg.
