I2C: mxc_i2c: make I2C1 and I2C2 optional

The driver assumed that I2C1 and I2C2 were always enabled,
and if they were not, then an asynchronous abort was (silently)
raised, to be caught much later on in the Linux kernel.

Fix this by making I2C1 and I2C2 optional just like I2C3 and I2C4
are.

To make the change binary-invariant, declare I2C1 and I2C2 in
every include/configs/ file which defines CONFIG_SYS_I2C_MXC.

Also, while updating README about CONFIG_SYS_I2C_MXC_I2C1 and
CONFIG_SYS_I2C_MXC_I2C2, add missing descriptions for I2C4 speed
(CONFIG_SYS_MXC_I2C4_SPEED) and slave (CONFIG_SYS_MXC_I2C4_SLAVE)
config options.

i2c: mxc: refactor i2c driver and support dm

1. Introduce a new structure `struct mxc_i2c_bus`, this structure will
used for non-DM and DM.
2. Remove `struct mxc_i2c_regs` structure, but use register offset to access
registers based on `base` entry of `struct mxc_i2c_bus`.
3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform
flags. A new flag is introduced, I2C_QUIRK_FLAG.
4. Most functions use `struct mxc_i2c_bus` as one of the parameters.
Make most functions common to DM and non-DM, try to avoid duplicated code.
5. Support DM, but pinctrl is not included. Pinmux setting is still set
by setup_i2c, but we do not need bus_i2c_init for DM.
6. struct i2c_parms and struct sram_data are removed.
7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist
paramter of bus_i2c_init is modified to i2c index. Add new prototype
i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for
DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus.
Board file take the responsibility to implement this function, like this:
"
int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus)
{
if (i2c_bus->index == 0)
force_bus_idle(i2c_pads_info0);
else if (i2c_bus->index == 1)
force_bus_idle(i2c_pads_info1);
else
xxxxxx
}
"
8. Introduce a weak function, enable_i2c_clk
9. Tested on an i.MX7 platform. Log info:

i2c:mxc fix array size of i2c_data

We should not hardcode array size of i2c_data to 3. To CONFIG_FSL_LSCH3,
there are 4 i2c interface, but not 3. So the size of i2c_data array should
be calculated using "ARRAY_SIZE(i2c_bases)".

To avoid compile error, move i2c_bases before sram_data structure which
contains i2c_data array.

ARMv8/FSL_LSCH3: Add FSL_LSCH3 SoC

Freescale LayerScape with Chassis Generation 3 is a set of SoCs with
ARMv8 cores and 3rd generation of Chassis. We use different MMU setup
to support memory map and cache attribute for these SoCs. MMU and cache
are enabled very early to bootst performance, especially for early
development on emulators. After u-boot relocates to DDR, a new MMU
table with QBMan cache access is created in DDR. SMMU pagesize is set
in SMMU_sACR register. Both DDR3 and DDR4 are supported.
