drivers/i2c/fsl_i2c: modify i2c_read to handle multi-byte write

Most of the I2C slaves support accesses in the typical style
that is : read/write series of bytes at particular address offset.
These transactions look like:"
(1) START:Address:Tx:Offset:RESTART:Address[0..4]:Tx/Rx:data[0..n]:STOP"

However there are certain devices which support accesses in
terms of the transactions as follows:
(2) "START:Address:Tx:Txdata[0..n1]:Clock_stretching:
RESTART:Address:Rx:data[0..n2]"
Here Txdata is typically a command and some associated data,
similarly Rxdata could be command status plus some data received
as a response to the command sent.

Type (1) transactions are currently supportd in the
i2c driver using i2c_read and i2c_write APIs. I2C EEPROMs,
RTC, etc fall in this category.

To handle type (2) along with type (1) transactions,
i2c_read() function has been modified.

fsl_i2c: add workaround for the erratum I2C A004447

This workaround is for the erratum I2C A004447. Device reference
manual provides a scheme that allows the I2C master controller
to generate nine SCL pulses, which enable an I2C slave device
that held SDA low to release SDA. However, due to this erratum,
this scheme no longer works. In addition, when I2C is used as
a source of the PBL, the state machine is not able to recover.

At the same time, delete the reduplicative definition of SVR_VER
and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16
bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro
instead of hard-code value 0x10, 0x11 and 0x20.

The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one
version of platform has this I2C errata. So enable this errata
by IS_SVR_REV(svr, maj, min) function.

fsl_i2c: generate nine pulses on SCL if the I2C bus is hung

When the code detected that the bus is hung (e.g. SDA stuck low),
send 9 pulses on SCL to try to fixup the bus.
