i2c: uniphier: issue STOP only for last message or I2C_M_STOP
[ Upstream commit 38f5d8d8cbb2ffa2b54315118185332329ec891c ]
This driver currently emits a STOP if the next message is not
I2C_MD_RD. It should not do it because it disturbs the I2C_RDWR
ioctl, where read/write transactions are combined without STOP
between.
Issue STOP only when the message is the last one _or_ flagged with
I2C_M_STOP.
