driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAMW2S CVE: NA

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

1. The initialization sequence of the edma_host.timer and edma_host is optimized when the iBMA initializes the edma driver. 2. Change the iBMA driver version.
