PCI/AER: Use explicit register sizes for struct members

aer_irq() reads the AER Root Error Status and Error Source Identification
(PCI_ERR_ROOT_STATUS and PCI_ERR_ROOT_ERR_SRC) registers directly into
struct aer_err_source.  Both registers are 32 bits, so declare the members
explicitly as "u32" instead of "unsigned int".

Similarly, aer_get_device_error_info() reads the AER Header Log
(PCI_ERR_HEADER_LOG) registers, which are also 32 bits, into struct
aer_header_log_regs.  Declare those members as "u32" as well.

No functional changes intended.
