----------------------------------------------------------------------
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.

Fixes: 300b796262a1 ("event/cnxk: add timer arm routine")
