autoboot: remove CONFIG_ZERO_BOOTDELAY_CHECK

Browse Source 
As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2
means the autoboot with no delay, with no abort check even if
CONFIG_ZERO_BOOTDELAY_CHECK is defined.

To sum up, the autoboot behaves as follows:

 [1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y
    autoboot with no delay, but you can abort it by key input

 [2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
    autoboot with no delay, with no check for abort

 [3] CONFIG_BOOTDELAY=-1
    disable autoboot

 [4] CONFIG_BOOTDELAY=-2
    autoboot with no delay, with no check for abort

As you notice, [2] and [4] come to the same result, which means we
do not need CONFIG_ZERO_BOOTDELAY_CHECK.  We can control all the
cases only by CONFIG_BOOTDELAY, like this:

 [1] CONFIG_BOOTDELAY=0
    autoboot with no delay, but you can abort it by key input

 [2] CONFIG_BOOTDELAY=-1
    disable autoboot

 [3] CONFIG_BOOTDELAY=-2
    autoboot with no delay, with no check for abort

This commit converts the logic as follow:
  CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
    --> CONFIG_BOOTDELAY=-2
