[PATCH v2 3/5] PCI: epf-mhi: Use a define for the DMA transfer timeout

[Sumit Kumar <sumit.kumar@oss.qualcomm.com>]

The eDMA read and write paths open-code a 1000 ms completion timeout as a
msecs_to_jiffies(1000) literal. Replace both with a
PCI_EPF_MHI_DMA_TIMEOUT_MS define so the value is named and shared. No
functional change.
