* add rt_i2c structure to store driver data
* rewrite read/write check function and add i2c error status check.
so we don't need to wait until time out.
* add 10 bits address support. according to the data sheet i think
it is possible. but i haven't verify it.
* the most important is start transfer only need once. otherwise
it cause I2C_STARTERR status.
* add set i2c clock speed register by dts options "clock-frequency".
not just hard code it.
* add mt7621 i2c driver. i just copy i2c-ralink.c and change register
names. and the hardware don't support error status. so i remove it.
but the logic is the same.

* fix compiler error. device_control operation not support now.
* add old chips support 8 channels. new chips support 16 channels.
* add mt7621 hsdma driver. data sheet says it has two channels.
but after test only one channel support.
* add memory to memory DMA support. i use dmatest kernel module to
verify this function. on rt305x it will copy more data. on mt7621
only two channels can works at the same time. these two chips
maybe have hardware bugs. because on other chips don't have these bugs.
* use tasklet to handle remaining dma requests.

This patch allows configuring ports to be disabled in the device tree; this
saves power, since disabling ports here actually disables power to ethernet
PHYs.
Line 444 enables all ethernet ports, so line 487 is getting zero ports to be
disabled, except for port 5 in SoCs where this is not implemented as it will
be sticky disabled in register POC0. Because of this, the code will still read
the switch configuration and OR it to the device tree setting.

Line 444 is actually enabling all switch ports by setting the disable bits
to 0. This needs to be done because the bootloader sets all ports to disabled
by default (which is the case for at least one router based on RT5350).
So, this patch fixes the comment in line 443.

The FCT2 esw register should be set to 0x2500C to have "unknown IPv6
multicast" packets broadcasted to every port, instead of dropped.
The previous value only let those packets go through ports 1 and 3.
"Unknown IPv6 multicast" packets include packets needed by ICMPv6 echo
requests addressed to well-known addresses, such as ff02::1 (MAC address
is 33:33:00:00:00:01 in this case).
Please note that by default ICMPv6 echo requests to ff02::1 are not replied
to by the router because of ip6tables considering those packets to be invalid.
But this is another bug/patch. ;)

Misc fixes for LinkIt 7688 board:
- Copy the right wireless firmware for the mt7688
- Add back '0065-mt7688-fixes.patch', left out after the move to Linux 4.4.
- Remove SPI_DEV from linux config which otherwise causes a massive warning
- Add wmac to LINKIT7688.dts so wireless works
