asm106x: add programmer for ASM106x SATA controllers
The ASMedia ASM106x series is a PCIe-SATA controller chip. It supports an attached SPI flash chip that can contain configuration and PCI option ROM. The interface is a simple shifter accessed via PCI config space, up to 4 bytes at a time. Add a programmer driver for it. Tested on a G536PCE1061V11 IO-PCE1061-V1.1 PCIe card, and a MPCE2ST-A01 VER006S mini-PCIe card, both with chips marked ASM1061, both enumerate as: 01:00.0 SATA controller [0106]: ASMedia Technology Inc. ASM1062 Serial ATA Controller [1b21:0612] (rev 02) (prog-if 01 [AHCI 1.0]) Subsystem: ASMedia Technology Inc.
