Entering the maximum number of characters defined by CONFIG_SYS_CBSIZE into the console and hitting enter afterwards, causes a hang in the system because CONFIG_SYS_PBSIZE is not capable of storing the extra characters of the error message: "Unknown command '' - try 'help'".

Use the default CONFIG_SYS_PBSIZE definition from config_fallbacks.h to solve this problem.

Perfoming an OR operation on the error is not a good approach.

Return the error immediately for each ESDHC instance instead.
