nios2: move include asm-generic/io.h to end of file

Move asm-generic/io.h to end of file to override functions like
phys_to_virt, virt_to_phys in asm-generic/io.h.
This is due to recent commit 9216efaf introduced new way to
override functions by checking for the existence of a macro with the
same of the function.

nios2: Remove write-only struct member from nios2_timer

The irq member of struct nios2_timer is only written to but never read,
thus it can be removed.

nios2: Add missing NR_CPUS to Kconfig

kernel/time/Kconfig expects that NR_CPUS is defined.

This fixes the following config warning:
"kernel/time/Kconfig:163:warning: range is invalid"

Follow 4cbbbb43d666 ("microblaze: Fix missing NR_CPUS in menuconfig")

nios2: Make NIOS2_CMDLINE_IGNORE_DTB depend on CMDLINE_BOOL

If NIOS2_CMDLINE_IGNORE_DTB is selected but CMDLINE_BOOL isn't and thus
CONFIG_CMDLINE is not defined, the build fails with the following error:

arch/nios2/kernel/setup.c: In function 'nios2_boot_init':
arch/nios2/kernel/setup.c:131:30: error: 'CONFIG_CMDLINE' undeclared (first use in this function)
   strncpy(boot_command_line, CONFIG_CMDLINE, COMMAND_LINE_SIZE);

This can be reproduced using randconfig with KCONFIG_SEED=0xE5B8749E, i.e.
'make KCONFIG_SEED=0xE5B8749E ARCH=nios2 randconfig'.

Fix this by letting NIOS2_CMDLINE_IGNORE_DTB depend on CMDLINE_BOOL, so we
actually have a default kernel command string to fall back to.
