[ARM] pxa: introduce reset_status and clear_reset_status for driver's usage
Due to the problem of reset status bits being handled by different registers between pxa2xx and pxa3xx, introduce a global reset_status variable, initialized by SoC-specific code and later being used by other drivers. And also introduce clear_reset_status(), which is used to clear the corresponding status bits. Pass RESET_STATUS_ALL to clear all bits. Signed-off-by: Eric Miao <eric.miao@marvell.com>
