When high performance with multiple i2c messages in a single transfer

For each i2c message transfer, a series of Transfer Request Elements(TREs)
must be programmed, including config tre for frequency configuration,
go tre for holding i2c address and dma tre for holding dma buffer address,
length as per the hardware programming guide. For transfer using BEI,
multiple I2C messages may necessitate the preparation of config, go,
and tx DMA TREs. However, a channel TRE size of 64 is often insufficient,
potentially leading to failures due to inadequate memory space.
Please kindly test the patches before you sent them. Upstream is not a
testing service.
Sure, i will take care to test the required patches.
Best regards,
