Subject: [PATCH] esp32/boards: Increase 512 bytes limit on ULP programs to
 2040.

Allow esp32.ULP.load_binary() to use the maximum amount of memory available
again, which is 2040 bytes unless MICROPY_HW_RTC_USER_MEM_MAX is
customized.

This value regressed in 3d49b157b89a59774fc4958dcaacd2c96ba6eaa4
