When the Cr50 starts up it doesn't have a valid locality. The driver sets
it to -1 to indicate that. Tracking this allows cr50_i2c_cleanup() to
avoid releasing a locality that was not claimed.
However the helper functions that generate the flags use a u8 type which
cannot support -1, so they return a locality of 0xff.
Fix this by updating the type. With this, 'tpm startup TPM2_SU_CLEAR'
works as expected.

This patch adds support for MTK SPI NOR controller, which you
can see on mt7622 & mt7629.
1. This controller is designed only for SPI NOR. We can't adjust
its bus clock dynamically. Set clock in dts instead.
2. This controller only supports 1-1-1 write mode.
3. Remove mtk_snor_match_read() since upper SPI-MEM layer already
handles command.
4. sf read/write/update commands are tested with this driver.

On my DS414, some PCI devices return odd values when probing BAR sizes.
An obvious case is all-ones response, the Linux driver
(drivers/pci/probe.c) catches those explicitly and a comment explains
that either bit 0 or bit 1 must be clear (depending on MEM or IO type).
Other BARs return e.g. 0xfff0000f or 0xfff00004 and thus manage to break
size calculation due to the "middle" zeroes. Mitigate that copying more
or less what Linux does and do a "find least bit set".

So far the only difference between the various Allwinner MMC controller
we are concerned about is the mod clock register offset.
This is actually not directly related to the MMC controller IP, but an
integration choice, dependent on the SoC this appears in.
To avoid becoming trapped with some compatible fallback strings, let's
remove the whole struct sunxi_mmc_variant, and replace this with a SoC
based choice, which we can derive from the CONFIG_MACH_SUNx_y symbols.
This will later simplify H616 support.

So far all GBit users of the sun8i-emac driver were using the "rgmii"
PHY mode, even though this turns out to be wrong. It just worked because
the PHY driver doesn't do the proper setup (yet).
In fact for most boards the "rgmii-id" or "rgmii-txid" PHY modes are the
correct ones.
To allow the DTs to describe the phy-mode correctly, and to stay
compatible with Linux, at least allow those other RGMII modes in the
driver.
This avoids breakage if mainline DTs will be synced with U-Boot.
