Most FPGA devices themselves are SRAM-based, so no practical limit.

Some setups use (SPI) flash-based devices to store the FPGA configuration; 
they therefore have a limited lifetime. Yet others are configured directly 
from micro-controller, so your limit is whatever media you're reading the 
bitstream from.
