kconfig: do not overwrite symbol direct dependency in assignment
Considering the following configuration:
config F
bool "F"
choice AB
bool "AB"
config A
bool "A"
config B
bool "B"
endchoice
if A
config D
bool
default y if F
select E
config E
bool "E"
endif
if B
config D
bool
default y if F
select E
config E
bool "E"
endif
The following configuration:
CONFIG_F=y
CONFIG_A=y
# CONFIG_B is not set
CONFIG_D=y
CONFIG_E=y
emits a spurious warning:
(D) selects E which has unmet direct dependencies (B)
If a symbol appears in two different branch of the tree, it should inherit the
dependency of both parent, not just the last one.
