Masahiro Yamada b08d15cc92 i2c: uniphier-f: issue STOP only for last message or I2C_M_STOP
[ Upstream commit 4c85609b08c4761eca0a40fd7beb06bc650f252d ]

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.
