ioremapped virtual address is only used by kenrel drivers
who need to access pmem. But on our platform, we never have
such use case. So remove this ioremap to save the vmalloc
virtual kernel spaces for lowmem mapping.

the driver would have chance to do platform specific init and exit

Workaround for imx5x M4IF burst len errata when armv7 neon enabled:
if the burst len > 8bytes, access the strongly ordered memory,
the result is not correct.
Use pgprot_writecombine to map the memory to uncached and normal memory type,
instead of pgprot_noncached which maps to strongly ordered memory,
to avoid burst len > 8.

	add performance monitor driver.
	sample:
		cd /sys/devices/platform/mxs-perfmon.0/
   		'echo 1 > MIDn-xxx' to enable monitor this channel
			n: channel number; xxx: name of channel (PXP, LCD...)
			you can enable the multiple channels you want to
			monitor respectively using this command.
			use following command to check the channel is enabled
		'cat MIDn-xxx'
			1: enable; 0: disable

		'echo read > Monitor' to monitor all read activities
		'echo start > Monitor' to start monitoring
		'echo fetch > Monitor' to get a snapshot of monitor statistics.
		'cat xxx_Count' to show the statistics.
			xxx: name of statistics, (Data, Transfer, Latency...)

		'echo clear > Monitor' to clear snapshot of monitor statistics.
		'echo stop > Monitor' to stop monitoring
