In include/linux/mailbox/zynqmp-ipi-message.h, it says that
the maximum length of data buffer is fixed to 12 bytes. So
define payload array length to 12 to fix compile warning as
below:
drivers/soc/xilinx/zynqmp_power.c:91:2: warning: ISO C90 forbids variable
length array 'payload' [-Wvla]
91 | u32 payload[msg->len];
| ^~~
