qcacmn: Add wmi wrapper function for mtrace logging

For qdf_mtrace 15 bits are reserved for message id and currently
WMI message IDs are getting used as 32 bit IDs.

Write a wrapper function which accepts 32 bit message IDs and
converts this 32 bit message id to 15 bit by extracting
WMI_GRP_ID and WMI_MESSAGE_ID in that group. New 15 bit
message ID for qdf_mtrace will be constucted as 8 bits
(From LSB) specifies the WMI_GRP_ID and remaining 7 bits
specifies the actual WMI command. With this notation there
can be maximum 256 groups and each group can have max 128
commands which can be supported.
