MAINTAINERS: rectify file entry in ALIBABA PMU DRIVER

Commit cf7b6107 ("drivers/perf: add DDR Sub-System Driveway PMU driver
for Yitian 710 SoC") adds the DDR Sub-System Driveway PMU driver here:

  drivers/perf/alibaba_uncore_drw_pmu.c

The file entry in MAINTAINERS for the ALIBABA PMU DRIVER, introduced with
commit d813a19e ("MAINTAINERS: add maintainers for Alibaba' T-Head PMU
driver"), however refers to:

  drivers/perf/alibaba_uncore_dwr_pmu.c

Note the swapping of characters.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken file pattern.

Repair this file entry in ALIBABA PMU DRIVER.
