This patch replaces the horribly coded of_count_named_gpios() with a
call to of_count_phandle_with_args() which is far more efficient. This
also changes the return value of of_gpio_count() & of_gpio_named_count()
from 'unsigned int' to 'int' so that it can return an error code. All

This patch creates of_count_phandle_with_args(), a new function for
counting the number of phandle+argument tuples in a given property. This
is better than the existing method of parsing each phandle individually
until parsing fails which is a horribly slow way to do the count.
It also converts

The of_gpio_named_count() self test doesn't hit the out-of-range
condition even though it is coded. Fix the bug by increasing the for
loop range by one.

befs_sb->num_blocks is of base type u64 which is the same as sector_t.
Therefore, num_blocks can never be larger then the maximum
value of sector_t.
