    libpayload: x86: correct types used for writel/readl
    
    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 types with the 32-bit fixed width ones that
    are exposed.
