mx6: Add workaround for ARM errata
Add workaround for the following ARM errata: 743622 and 751472.
The motivation for this change is the following kernel commit 62e4d357a
(ARM: 7609/1: disable errata work-arounds which access
secure registers), which removes the errata from multiplatform kernel.
Since imx has been converted to multiplatform in the kernel, we need to apply
such workarounds into the bootloader.
Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel.
Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad"
document available at: cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf

Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."

In e1000e driver, Rx descriptor queue is used such that hardware can add only
one descriptor at a time. So the WTHRESH granularity in RXDCTL should be set
to single descriptor. This would ensure that every time controller fills a Rx
descriptor, it is flushed to host memory. Earlier this granularity was in
cache line units i.e 2 descriptors. This leads to controller always waiting
for 2 descriptors before flushing them out. But since not more than one Rx BD
is actually available , the accumulation condition never gets hit.

It could happen (1 out of 100 times) that NAND did not start up correctly after
warm rebooting, so we end up with various failures or DMA timed out due to a
stalled BCH. When resetting BCH together with GPMI, the issue could not be
observed anymore (after 10000+ reboots). We probably need the consistent state
already before sending commands to NAND. This behaviour was observed in barebox
and kernel, so I assume it affects U-Boot as well. I chose to keep the extra
reset for BCH when changing the flash layout to be on the safe side.

designware_i2c: Fixed the setting of the i2c bus speed
There are three couple (hcnt/lcnt) of registers for each
speed (SS/FS/HS). The driver needs to set the proper couple
of regs according to what speed we are setting.
In the newer versions of designware i2c IP there is the possibility
of configuring it with IC_EMPTYFIFO_HOLD_MASTER_EN=1, which basically
requires the s/w to generate the stop bit condition directly, as
the h/w will not automatically generate it when TX_FIFO is empty.
To avoid generation of an extra 0x0 byte sent as data, the
IC_STOP command must be sent along with the last IC_CMD.
This patch always writes bit[9] of ic_data_cmd even in the
older versions, assuming that it is a noop there.
