The following LLVM compile error is observed in sbi_mpxy.c:

 CC        lib/sbi/sbi_mpxy.o
lib/sbi/sbi_mpxy.c:535:36: error: result of comparison of constant 18446744073709551615 with
      expression of type 'u32' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
  535 |                     (attrs->msi_info.msi_addr_hi == INVALID_ADDR))

      expression of type 'u32' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]

2 errors generated.

To address the above issue, add u32 typecast to INVALID_ADDR.

Fixes: e92c8fd083 ("sbi: mpxy: define INVALID_ADDR using unsigned long width")
Fixes: 7939bf1329 ("lib: sbi: Add SBI Message Proxy (MPXY) framework")
