We do not want to have two entries to cache the guest configuration registers: XenPTReg->data and dev.config. Instead we want to use only the dev.config. To do without much complications we rip out the ->data field and replace it with an pointer to the dev.config. This way we have the type-checking (uint8_t, uint16_t, etc) and as well and pre-computed location. Alternatively we could compute the offset in dev.config by using the XenPTRRegInfo and XenPTRegGroup every time but this way we have the pre-computed values. This change also exposes some mis-use: - In 'xen_pt_status_reg_init' we used u32 for the Capabilities Pointer register, but said register is an an u16. - In 'xen_pt_msgdata_reg_write' we used u32 but should have only use u16.
