Tom Fifield f127702bef Fix GPS Buffer full issue on NRF52480 (Seeed T1000E) (#8956)
We set the buffer size to about a byte on NRF52480, less than
other platforms:

esp32.ini:  -DSERIAL_BUFFER_SIZE=4096
esp32c6.ini:  -DSERIAL_BUFFER_SIZE=4096
nrf52.ini:  -DSERIAL_BUFFER_SIZE=1024

However, 115200 baud, like the T1000e uses is about 12 times that
- almost 15 bytes per millisecond.
15 bytes * 200 millisecond (our GPS poll rate)  = 3000 bytes, which is longer than our buffer
on the nrf52 platform. This causes "GPS Buffer full" errors on the T1000e
and other devices based on NRF52480 with newer GPS chips.

This patch increases SERIAL_BUFFER_SIZE for nrf52480 to 4096 to align with
other platforms. It keeps the original 1024 for the nrf52832, which has
fewer resources.

; Common NRF52 debugging settings follow. See the Meshtastic developer docs for how to connect SWD debugging probes to your board.
; We want the initial breakpoint at setup() instead of main(). Also we want to enable semihosting at that point so instead of
debug_init_break = tbreak setup
; we just turn off the platformio tbreak and do it in .gdbinit (where we have more flexibility for scripting)
; also we use a permanent breakpoint so it gets reused each time we restart the debugging session?
; debug_init_break = tbreak main

; IMPORTANT: fileio must be disabled before using port 5555 - openocd ver 0.12 has a bug where if enabled it never properly parses the special :tt name

; monitor arm semihosting_redirect tcp 5555 stdio
; Also note: it is _impossible_ to do non blocking reads on the semihost console port (an oversight when ARM specified the semihost API).
; So we'll neve be able to general purpose bi-directional communication with the device over semihosting.
