libpayload: x86: correct types used for IO

libpayload on x86 defines u32 and uint32_t as typedefs of
    unsigned int. However, the readl/writel routines use long.
    With alias checking this throws type punning errors. Align
    the readl/writel/inl/outl types with the 32-bit fixed width
    ones that are exposed.
