Build with Clang-10 has warning:
drivers/event/cnxk/cnxk_tim_worker.h:372:23: warning: value size does not match register size specified by the constraint and modifier [-Wasm-operand-widths]
                             : [rem] "=&r"(rem)
                                           ^
drivers/event/cnxk/cnxk_tim_worker.h:365:17: note: use constraint modifier "w"
                             "          ldxr %[rem], [%[crem]]  \n"
                                             ^~~~~~
                                             %w[rem]

Changed variable type to match register size, which placates clang.
