W83627DHG: - Add proper "virtual LDN" handling for the LDNs that need it (i.e., those that don't have their "enable" bit in bit 0 of the 0x30 register). - Fix various I/O masks in the pnp_dev_info[] array as per datasheet. Add missing PNP_IRQ0 to the W83627DHG_ACPI LDN. W83627EHG: - Similar to W83627DHG, improve the "virtual LDN" setup a bit (it was mostly implemented already, though). - Add missing PNP_IRQ0 to the W83627EHG_ACPI LDN. Also: Fix up devicetree.cb of all boards using W83627DHG/W83627EHG to adapt for the virtual LDNs. include/device/pnp.h: Add comment that 'function' (which refers to the LDN and should probably be renamed later) has to be at least 16 bits wide. In theory LDNs could use u8, but due to the virtual LDN info being encoded in the "high byte" of 'function' it must be at least u16. asrock/939a785gmh/romstage.c: Drop unused GPIO6_DEV. ibase/mb899/romstage.c: Use DUMMY_DEV instead of a specific LDN (serial port 1 in this case) to avoid confusion. The global registers manipulated there are accessible from any LDN.
