A single menu within an if like
if FOO
menu "blah"
...
endmenu
endif
can be replaced with
menu "blah"
depends on FOO
...
endmenu
Fix up all existing instances.
Also remove redundant extra menus underneath 'menuconfig' symbols.
'menuconfig' already creates a menu.
Also remove the menu in arch/arm/core/aarch32/Kconfig around the
"Floating point ABI" choice. The choice depends on FLOAT, which depends
on CPU_HAS_CPU, so remove the 'depends on CPU_HAS_FPU' too.
Piggyback removing a redundant 'default n' for BME280.
