mb/siemens/mc_apl{3,5}: Remove __weak symbol from GPIO functions

The two GPIO functions variant_gpio_table() and
variant_early_gpio_table() provide the pointer to the variants GPIO
table for late and early GPIO init. As these functions are variant
dependent the keyword __weak must not be used as otherwise the linker
might choose the tables from the baseboard.

This patch removes the __weak definition making these functions
overriding the general ones in baseboard/gpio.c.
