ACPI dock: move some functions to .init.text

find_dock and find_bay are only called by dock_init which lives in
.init.text dock_add is only called by find_dock and find_bay.  So all
three functions can be moved to .init.text, too.

This fixes:

        WARNING: vmlinux.o(.text+0x2134b7): Section mismatch in reference from the function dock_add() to the function .init.text:platform_device_register_resndata()
        The function dock_add() references
        the function __init platform_device_register_resndata().
        This is often because dock_add lacks a __init
        annotation or the annotation of platform_device_register_resndata is wrong.

for a build with unset CONFIG_MODULES.
