v3 cover Support for XPedite5370 and misc GPIO

Hello,
This patch series adds support for the XPedite5370 SBC. Its an MPC8572-based VPX card with a PMC/XMC site. The XPedite5370 includes a significant number of I2C GPIO devices (5) which are used for board configuration. I added support for 2 new I2C gpio devices in a new drivers/gpio directory. I'm not sure if this is the preferred location/method, so let me know if others have have different preferences. It'd be nice to have a more generic GPIO framework (like Linux's) at some point, but figured this was a step in the right direction by providing a place for generic GPIO devices in drivers/gpio.

Thanks,
Peter

Changes since v1:
- Rebased to u-boot-mpc85xx tree
- Updated NOR flash remapping method
- Added CONFIG_SYS_I2C2_OFFSET define to XPEDITE5370.h
- Removed CONFIG_SYS_EEPROM_PAGE_WRITE_ENABLE from XPEDITE5370.h

Changes since v2:
pca953x.c:
- Use cmd_tbl_t for subcommand parsing
- Made 'info' command dependent on CONFIG_CMD_PCA953X_INFO
- Removed chip command parameters, added 'device' subcommand

ds4510.c:
- Use cmd_tbl_t for subcommand parsing
- Made 'info' command dependent on CONFIG_CMD_DS4510_INFO
- Made memory commands dependent on CONFIG_CMD_DS4510_MEM
- Made 'rst' command dependent on CONFIG_CMD_DS4510_RST
- Removed chip command parameters, added 'device' subcommand
- Fixed multiline comment style
- moved to drivers/misc

xpedite5370:
- Changed alignment by spaces to alignment by tabs
- Fixed gur->devdisr typo for PCIe2
- Fixed some lines over 80 chars
- Fixed multiline comment style
- Cleaned up environment defines

PATCH v3 1/3 Add support for PCA953x I2C gpio devices

Initial support for NXP's 4 and 8 bit I2C gpio expanders (eg pca9537, pca9557, etc). The CONFIG_PCA953X define enables support for the devices while the CONFIG_CMD_PCA953X define enables the pca953x command. The CONFIG_CMD_PCA953X_INFO define enables an 'info' sub-command which provides summary information for the given pca953x device.

PATCH v3 2/3 Add support for Maxim's DS4510 I2C device

Initial support for the DS4510, a CPU supervisor with integrated EEPROM, SRAM, and 4 programmable non-volatile GPIO pins. The CONFIG_DS4510 define enables support for the device while the CONFIG_CMD_DS4510 define enables the ds4510 command. The additional CONFIG_DS4510_INFO, CONFIG_DS4510_MEM, and CONFIG_DS4510_RST defines add additional sub-commands to the ds4510 command when defined.
