ARM: i.MX6UL: liteSOM: depend on DDR controller settings ...

Initially we depended on DDR controller settings for liteSOM and liteboard. With
33fdc89d4cbd ("dts: update to v5.0-rc1") a `device_type = "memory";` property
was added to imx6ul-litesom.dtsi file, which causes "ram0" to be added with
512MB size (value in dtsi) instead of the real 256MB size that is configured in
barebox-grinn-liteboard-256mb.img. As a result Linux kernel fails to boot.

Lets depend on DDR controller settings, by removing whole `/memory` node from
device tree. This makes barebox-grinn-liteboard-256mb.img able to boot Linux
kernel once again.

esdhc-xload: check for PRSSTAT_BREN only after each block ...

The BREN bit tells us a watermark level sized buffer is ready for read.
Instead of testing it before each FIFO read we must only check it once
and then read a watermark level sized buffer. This is at least necessary
on Layerscape, otherwise timeouts occur while reading the buffer.

esdhc-xload: Use static inline io wrappers ...

We'll need big endian support for Layerscape, so put the io accessors

i2c: i.MX: Add early driver for use in PBL ...

i2c is used in SPD EEPROMs and thus needed very early before barebox is
up. This patch adds a i.MX i2c driver variant for use in PBL.

Following the Linux driver the controller should be stopped in the

not when other transfers of the same message are following. Implement
this behaviour for the barebox driver aswell.
