ALSA: hda - Add the top speaker pin config for HP Spectre x360

HP Spectre x360 with CX20724 codec has two speaker outputs while the
BIOS sets up only the bottom one (NID 0x17) and disables the top one
(NID 0x1d).

This patch adds a fixup simply defining the proper pincfg for NID 0x1d
so that the top speaker works as is.
