Add Genesys Logic GL975x support

From: Ben Chuang <[email protected]>

The patches modify internal clock setup to match SD Host Controller Simplified Specifications 4.20 and support Genesys Logic GL9750/GL9755 chipsets.

V6:
- export sdhci_abot_tuning() function symbol
- use C-style comments
- use BIT, FIELD_{GET,PREP} and GENMASK to define bit fields of register
- use host->ops->platform_execute_tuning instead of mmc->ops->execute_tuning
- call sdhci_reset() instead of duplicating the code in sdhci_gl9750_reset
- remove .hw_reset
- use condition define CONFIG_MMC_SDHCI_IO_ACCESSORS for read_l

V5:
- add "change timeout of loop .." to a patch
- fix typo "verndor" to "vendor"

V4:
- change name from sdhci_gli_reset to sdhci_gl9750_reset
- fix sdhci_reset to sdhci_gl9750_reset in sdhci_gl9750_ops
- fix sdhci_gli_reset to sdhci_reset in sdhci_gl9755_ops

V3:
- change usleep_range to udelay
- add Genesys Logic PCI Vendor ID to a patch
- separate the Genesys Logic specific part to a patch

V2:
- change udelay to usleep_range

Ben Chuang (5):
mmc: sdhci: Change timeout of loop for checking internal clock stable
mmc: sdhci: Add PLL Enable support to internal clock setup
PCI: Add Genesys Logic, Inc. Vendor ID
mmc: sdhci: Export sdhci_abort_tuning function symbol
mmc: host: sdhci-pci: Add Genesys Logic GL975x support
