fix(ulp): correct target LP memory reservation limits

Browse Source 
The configured maximum should match each target's fixed LP/RTC
reservations so menuconfig does not advertise values that the linker
cannot support.

Keep the linker failure explicit about CONFIG_ULP_COPROC_RESERVE_MEM
because application RTC sections still share the remaining LP/RTC RAM.
