BMA/edma_drv: Fix DMA reset problem and change the version number. 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IA97VA


CVE: NA

-----------------------------------------

1. Resolved the problem that the DMA reset does not meet the
   expectation due to the mismatch between the register configuration
   and the communication transmission direction during DMA reset.
2. Change the iBMA driver version.
