* 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.

- Use default number of uarts (2) for rt288x/rt305x/rt3883/mt7620.
- Allow up to 3 uarts on MT7621 and MT7628.
- Remove unneeded SERIAL_8250_RT288X for MT7628.

The previous image creation code would have failed if the
unpadded kernel uImage size was less than 64 bytes from the
next erase block boundary. Fix that.

The bootloader on this device expects the kernel partition to end
on a 64k boundary. The last 64 byte of the kernel partition must
contain a valid uImage header (the fakeroot partition).

Currently, for RT5350 and MT7628, esw is marked as compatible with
"ralink,rt3050-esw". While this is true, the switches within RT5350
and MT7628 actually support more functionality than the RT3050 switch.
One such example is per-VLAN untagging, which is an important feature.
RT3352 is another example of this, but it already has an additional
compatible property, which allows to differentiate it from RT3050.
This commit adds such more specific properties for RT5350 and MT7628
as well.

- disable all ethernet ports except port 0 on MPR-A2
Port 0 is the only ethernet port on this router, so disable all other PHYs in order to save power.
- don't use a VLAN for the single ethernet port of the MPR-A2
Like A5-V11, this router only has one ethernet port.

This commit makes the following modifications to ramips dts files:
1. Add clkctrl node to all dtsi files (although not used for now)
2. Add clocks and clock-names properties to some nodes (usbphy, pci)
3. Add usbphy node for rt3050 (although not used for now)
4. Add clock-frequency to uart nodes in mt7621.dtsi and mt7628an.dtsi
These modifications, although not fully used at the moment, will make
it easier for FreeBSD to adopt and use LEDE ramips dts files with
minimal changes for easier maintenance.

This patch introduces serial0 aliases in the ramips DTS files, which can
then be used to denote the active console instead of relying on bootargs.
