Xu Yang 0bcd599a0f perf: imx_perf: fix counter start and config sequence 
[ Upstream commit ac9aa295f7 ]

In current driver, the counter will start firstly and then be configured.
This sequence is not correct for AXI filter events since the correct
AXI_MASK and AXI_ID are not set yet. Then the results may be inaccurate.
