mwifiex: add support for FW memory read/write operations

This patch adds support for FW memory read/write operations via debugfs.
This is useful during debugging FW issues.

Examples:

For reading FW memory location:
echo r 0x01ac > /sys/kernel/debug/mwifiex/mlan0/memrw
cat /sys/kernel/debug/mwifiex/mlan0/memrw

For writing FW memory location:
echo w 0x01ac 0x55aa > /sys/kernel/debug/mwifiex/mlan0/memrw
