Baoquan He e4c881d212 riscv: fix VMALLOC_START definition

[ Upstream commit ac88ff6b9d7dea9f0907c86bdae204dde7d5c0e6 ]

When below config items are set, compiler complained:

--------------------
CONFIG_CRASH_CORE=y
CONFIG_KEXEC_CORE=y
CONFIG_CRASH_DUMP=y
......
-----------------------

-------------------------------------------------------------------
arch/riscv/kernel/crash_core.c: In function 'arch_crash_save_vmcoreinfo':
arch/riscv/kernel/crash_core.c:11:58: warning: format '%lx' expects argument of type 'long unsigned int', but argument 2 has type 'int' [-Wformat=]
11 |         vmcoreinfo_append_str("NUMBER(VMALLOC_START)=0x%lx\n", VMALLOC_START);
   |                                                        ~~^
   |                                                          |
   |                                                          long unsigned int
   |                                                        %x
----------------------------------------------------------------------

This is because on riscv macro VMALLOC_START has different type when
CONFIG_MMU is set or unset.

arch/riscv/include/asm/pgtable.h:
--------------------------------------------------

Changing it to _AC(0, UL) in case CONFIG_MMU=n can fix the warning.
