6e3dc12754 mx35: Fix eSDHC clocks
Each eSDHC instance has a dedicated clock.

gd->sdhc_clk must also be set accordingly. This is good for the case only a
single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A
future patch will fix the multi-instance use case (initialization made directly
with fsl_esdhc_initialize()).

151d63cb91 mx35: Clean up lowlevel_init
Clean up mx35 lowlevel_init:
 - Indent with tabs.
 - Fix comments.
 - Use defined values instead of literal constants.
 - Use defined macros instead of duplicating code.
 - Use macro parameters with default values instead of #define'd configs.

e7bed5c2b3 imx: Use MXC_I2C_CLK in imx i2c driver
i2c didn't work on imx25 due to missing MXC_IPG_PERCLK. Now using
MXC_I2C_CLK on all imx systems using i2c.

82e1b543b5 mx35: Fix clock dividers
The clock dividers that were used do not match at all the reference manual. They
were either completely broken, or came from an early silicon revision
incompatible with the current one.

8e99ecd74b mxc: Define architecture identifier
Define ARCH_MXC for i.MX devices. This is useful to identify features or
behaviors common to all i.MX SoCs.

The i.MX28 is omitted because its architecture is a bit different (like imx/mxc
vs. mxs in Linux).

40f6fffee5 MX: serial_mxc: cleanup removing nasty #ifdef
The serial driver for iMX SOCs is continuosly changed if a
new SOC or not yet used port is used. CONFIG_SYS_<SOC>_<UART Port>
defines were used only to find the base address for the selected UART.
Instead of that, move the base address to the board configuration
file and drop all #ifdef from driver.
