CAS-Latency=2, Write Recovery Time tWR=2
The max. supported bus frequency is 66 MHz. Therefore, changed
threshold to switch from 1:1 mode to 2:1 from 80 MHz to 66 MHz.

On the TQM885D the measurement of cpuclk with the PIT reference
timer ist not necessary. Since all module variants use the same
external 10 MHz oscillator, the cpuclk only depends on the PLL
configuration - which is readable by software.

At 133 MHz the current SDRAM refresh rate is too fast
(measured 4 * 1.17 us).
CFG_MAMR_PTA changes from 39 to 128. This result
in a refresh rate of 4 * 7.8 us at the default clock
66 MHz. At 133 MHz the value will be then 4 * 3.8 us.
This is a compromise until a new method is found to
adjust the refresh rate.

Explicitly add in default CONFIG_BOOTP_* options where cmd_confdefs.h
used to be included but CONFIG_BOOTP_MASK was not defined.
Remove lingering references to CFG_CMD_* symbols.
