tools: zynqmp: Fix regex expression around XPm_ConfigObject

The XPm_ConfigObject array definition generated by Vitis 2020.1 differs
from previous Vivado versions (before 2019.2).

-const u32 XPm_ConfigObject[] __attribute__((used, section(".sys_cfg_data"))) = {
+const u32 XPm_ConfigObject[] __attribute__((used, section(".sys_cfg_data"))) =
+#elif defined (__ICCARM__)
+#pragma location = ".sys_cfg_data"
+__root const u32 XPm_ConfigObject[] =
+#endif
+{

Change the matching regex to handle both cases.
